Andreas Klein is widely admired as a pianist of rare sensitivity and musicality. The Washington Post has praised his “articulate and flowing pianism” while the New York Times called him “a pianist who makes silences sound like music.” About a recent Glenn Gould tribute (with the Minguet String Quartet), the Calgary Herald reported, “(Klein brings) to his performance a mature understanding…as well as a brilliant execution”, while Classical Voice of North Carolina (CVNC) was even more blunt: “Andreas Klein is a stupendous pianist…a stunning performance by any standard, and it brought the audience to its feet in a rousing ovation.”  

He has performed in many of the leading houses of Europe, from Wigmore Hall in London to the Berlin Philharmonie, as well as Carnegie Hall in New York and the Kennedy Center in Washington DC, and is at home with the grandeur of playing with the Berlin Philharmonic or the vast reaches of the Ravinia Festival (where he received two standing ovations) as he is with the intimacy of Le Poisson Rouge (NYC). He has extensively toured North America, with ensembles including the Salzburg Chamber Soloists (a 20-city tour) and the Festival Strings of Lucerne (10 cities) and in South America, where he performed Beethoven’s Piano Concerto No. 4 in Peru, Chile, Argentina, Colombia, and Brazil. Some exotic places on his concert tours included Damascus and Yerevan.  

Since his meteoric start in his native Germany, performing recitals and as soloist with orchestra, he eventually answered the call to go to the Juilliard School in New York. But the highly focussed and musical approach to every work he performs was nurtured by one of his early teachers, the great Claudio Arrau. It is a philosophy Klein is credited with continuing.

In recent years Klein has added more forays into chamber music alongside his concerto and recital repertoire, including major projects with the Minetti Quartet and the Casals Quartet (Schumann's Piano Quintet - US tour and Casals Festival, Puerto Rico). These collaborations have taken him to important venues such as Philadelphia's Kimmel Center, Spivey Hall near Atlanta and the Wortham Center in Houston.  A frequent broadcaster, Klein has often appeared on WGBH Boston, WFMT Chicago,  APR in ST Paul and KUHF in Houston.

He was the subject of a "Musician Portrait" in Germany and his "Intermezzo with Andreas Klein" was televised by PBS. His recordings, "Piano Sonatas" and his album of music by Beethoven and Berg, have won admiring reviews (he is also an admired recording producer). And his self-composed new cadenzas for Mozart piano concertos have also won widespread praise. "Whatever the composer, whatever the project," he says, "for me it is about being inside the music."

Excerpts from the press

"Pianist who makes silences sound like music"
New York Times

"Sensitive interpretation"
The Times London

‍‍"Elaborate display of technical prowess. Klein resembled a sketch artist bringing a scene to life with quick virtuoso strokes and shading - Klein conveyed an impression of narrative momentum underlying a musical structure, regardless of how explicitly programmatic."
Washington Post

"Klein is an Interpret above all modern, who gives detailed attention to the interpretation of the work and executes a clear picture of the structure of the piece. He accomplishes with immaculate technique a rare beauty of sound."
Stampa Sera, Rome, Italy

SURPASSING MUSICALITY - "... played without unnaturalness, often somewhat fragile in tone, delicate, but with strong endings."
Berner Zeitung, Switzerland

"Andreas Klein, a pianist of the highest caliber, performed both Beethoven Sonatas in E major, opus 109, and in A major, opus 101, with dramatic expression, bravura, and a flawless technique: yet the slow and lyrical phrases were shaped with subtle sensitivity."
Dresdner Neueste Nachrichte, Germany

A LISTENING INDULGENCE - "The interpretation of Schubert's Impromptu in B flat major belongs to one of the most beautiful pieces presented in this concert. Klein played ingeniously, each single note differentiated, vivid and in every regard intended."
Berliner Morgenpost, Germany

"Andreas Klein played this work with grace, melodious sound and plenty of brilliance, revealing an immaculate technique." (with the Berlin Philharmonic)
Tagesspiegel, Berlin, Germany

"Impeccable technique, a distinct understanding for Mozart's pianistic style using muted dynamics and resonant touch." (with the Berlin Philharmonic)
Der Abend, Berlin, Germany

CONCERT OF AN EXTRA CLASS - "The virtuoso Klein, a pianist counted among the extraordinary class was able to set a new milestone into the history of the Mosel Festival."
Rhein Zeitung

"Klein's Beethoven was spot-on. In tender moments, such as the Andante, the pianist brought to the music great sensitivity and mystery, and where the score turns boisterous, such as his solo cadenza, Klein tapped reserves of power that seemed limitless."
Plain Dealer

Recent Reviews

"Internationally renowned concert pianist Andreas Klein joined forces with the Stockton Symphony to tackle Beethoven's Piano Concerto No. 4. His precision and communication with conductor Peter Jaffe made this daunting work a thing of beauty and brilliance. The contrasting dialogue between piano and strings in the brief but moving second movement evoked conflict and sadness, which is soon eclipsed by the ecstatic rondo of the third movement.

A bright, unmistakably Schubertian opening sets the tone for the piece. From Klein's first entry throughout the entire Liszt's Schubert Fantasie he played with articulate clarity while displaying expressive technique and craftsmanship. I was particularly taken with his voicing in the slow, second section, one of two solo passages that featured Klein. The ensemble between orchestra and soloist was excellent, providing an uninterrupted flow from beginning to end. Perhaps the most exciting moment was the return of the opening theme in the final section, scored in fugal imitation propelling the fantasy to its grandiose conclusion, where one could not help but hear Liszt's impact on the work."

The Post Crescent"

Magnificent and impressive was Andreas Klein in Beethoven's 4th Piano Concerto. In his entire interpretation he gave back the composers torment between intellect and emotion and with the superb command of his technique, the loud passages were never aggressive, his tonal colors were limitless, his scales always sparkled. Most gripping and impressive was his huge dynamic range; his control to produce a flawless shading down to a barely audible sound was breathtaking."

Grevenbroicher Zeitung, Germany

"Your performance was nothing short of spectacular. I still have people saying to me that they were blown away by the performance and the experience. And the sponsor was thrilled with performance and the reaction of the public.
Fundacion Paiz para la Educacion y la Cultura, Guatemala

"Maestro Andreas Klein's impeccable execution, his excellent sense of voicing - a rare caliber of musician - It was only a pity to realize the absence, with few exceptions, of other pianists, musicians and artists, who would have been able to take advantage and enjoy the excellent performance of maestro Klein. The combination of skill and affection he showed as an interpreter was of a quality rare to find in a soloist. Thank you, maestro."

“Three voices – one sound: it´s this absolutely perfect unit of phrasing, sound, feel and interpretation that distinguishes the ATOS Trio from all others” - Detroit Free Press                                                                           

Formed in Berlin, Germany in 2003  the ATOS Trio has established itself as one of the finest piano trios performing before the public today.  After intensive studies with Ilan Gronich, Menahem Pressler and the Alban Berg Quartet, the Trio won the Deutsche Musikwettbewerb, the Kalichstein-Laredo-Robinson International Trio Award and the Melbourne Chamber Music Competition. A New Generation Artists Award from the BBC and a Borletto Buitoni Award soon followed.  

Since then, the ATOS Trio has performed in many of the world's prestigious halls - at Carnegie Hall New York, Teatro Colon Buenos Aires, Wigmore Hall London, the Concertgebouw Amsterdam and the Berlin Philharmonic Kammersaal, to name but a few - with a repertoire that includes all the piano trio masterworks as well as many a lesser known treasure and contemporary pieces.

"They were Austrians in Haydn, Czechs in Dvorak, and Russians in Shostakovich."
O Estado de Sao Paulo, Brazil

"... One of the elite Piano Trios playing before the public today."
The Washington Post, USA

“The ATOS Trio performs with extraordinary presence and clarity, with an insisting intensity, always powerful and accentuated, with pose and aplomb, but at the same time heartfelt.”

Composer / Conductor
Avner Dorman writes music of intricate craftsmanship and rigorous technique, expressed with a soulful and singular voice. A native of Israel now living in the United States, Dorman draws on a variety of cultural and historical influences in composing, resulting in music that affects an emotional impact while exploring new territories. His works utilize an exciting and complex rhythmic vocabulary, as well as unique timbres and colors in orchestral, chamber, and solo settings. The world's finest orchestras, conductors, and soloists regularly perform Dorman's music, and many of his compositions have become contemporary staples in the repertoire. Dorman's music is championed by conductors including Zubin Mehta, Ricardo Chailly, and Andris Nelsons, and by soloists Gil Shaham, Martin Grubinger, and Hilary Hahn.

Dorman's first opera, Wahnfried, which garnered intense media interest and was hailed as a "masterpiece" by Opernwelt, returns to Karlsruhe in the 2017-2018 season for a second run as part of the Badisches Staatsoper staging of Wagner's complete ring cycle. The work - which depicts the relationships between the failing English scientist Houston Stewart Chamberlain, the Wagner family and the young Adolf Hitler - has culminated in a decisive round of "bravos" from the critics.

Dorman is currently working on a new, innovative opera project for Houston Grand Opera, which will make its debut in the spring of 2018. A new suite, for Solo Violin, commissioned by the ARD competition in Munich as a compulsory work, will be premiered there this fall.  Four Marimbas, commissioned by Jianli Percussion, will receive its world premiere in Spain, and Dancing with the Torah at Mount Meron premieres in Poland, performed by Zofo piano duo.

Other highlights of the 17-18 season include multiple performances of Nigunim, featuring violinist Gil Shaham, Mandolin Concerto featuring Avi Avital and Kremarata Baltica, Jerusalem Mix, featuring Ensemble 4.1, and Variations on a Simple Theme, featuring the Myriad Trio. Dorman's popular percussion concertos, Frozen in Time and Spices, Perfumes, Toxins!, will also be played by a variety of soloists and orchestras around Europe.

Other highlights from recent seasons include: the world premieres of Piano Sonata No. 5, written for the Arthur Rubinstein Piano Competition, Siklon, premiered by the Cleveland Orchestra, and After Brahms, which premiered in 2016 and has already received a dozen performances, including a run with the Sydney Symphony conducted by Asher Fisch.

In the fall of 2017, Dorman begins his fifth year as music director of CityMusic Cleveland Chamber Orchestra, with five performances of John Corigliano's Red Violin Concerto with acclaimed violinist Tessa Lark. The program also includes Schumann's Symphony No. 3 and Genoveva Overture. Later in the season he will lead CityMusic Cleveland in a concert dedicated to Muslim and Jewish composers and to the striking stories of the Sarajevo Haggadah and the Timbuktu library. The season closes with an all-Beethoven program.

Dorman's music has garnered numerous awards and prizes. At the age of 25, he became the youngest composer to win Israel's prestigious Prime Minister's Award for his Ellef Symphony. He has earned several international awards from ASCAP, ACUM, and the Asian Composers League. His music is available on Naxos, Deutsche Grammophone, Canary Classics, and other labels. He holds a doctorate in composition from the Juilliard School and serves as Associate Professor of Music Theory and Composition at the Sunderman Conservatory of Music at Gettysburg College.

Avner Dormans music is published exclusively by G. Schirmer, Inc.

Anne Midgette, Washington Post

“Dorman skillfully led the 40-piece chamber orchestra in nuanced and nearly flawless performances ”

Daniel Hathaway, Cleveland Classical

“The orchestra under Dorman was similarly effective.”

Mark Satola, The Plain Dealer

"The performance under Dorman, full of fire and vim, was uncommonly spirited.”

Other conductors who have influenced his career include Riccardo Frizza, Donato Renzetti, Dima Slobodeniouk, Christopher Seaman, Jesús Lopez Cobos, Titus Engel and Lutz Köhler.

Excerpts from the press

"Most crucial to the evening’s success was Diego Martin-Etxebarria, Chemnitz’s principal resident conductor, who expertly marshalled Verdi’s marches and choruses while highlighting subtleties of orchestration in between. The Met’s monumental, literal-minded “Aida” has accustomed me not to think too much about Verdi’s final grand opera; the team in Chemnitz goes considerably deeper."
The New Yorker

"Maestro Diego Martin-Etxebarria dealt with all the musical and theatrical material with the ability and security of someone well seasoned and well trained in many pits. His work seemed to me meritorious and demanded a great concentration to have everything ordered and channeled."
Mundo Clásico

"One quickly got used to the open sound in the empty auditorium, especially since Diego Martin Etxebarria with the Niederrheinische Sinfoniker developed an excellent sound volume, colorfulness and delicacy, with which the orchestra meticulously supported the psychogram on stage."
O-Ton Kulturmagazin

"Diego Martin-Etxebarria's splendid baton was able to transmit the sonorous essence of the score, conducting an ORCAM very much in keeping with the approach."
Ópera Actual

"Diego Martin-Etxebarria's musical direction renounced to traditional consecration and grandeur and celebrated a highly modern Mozart with elegance and fluent liveliness. The Niederrheinische Sinfoniker played with stylistic confidence - I would even say with outstanding virtuosity. We haven't heard such a convincing Mozart in a long time - to do so one has to drive far."

FOUR wind soloists from top German Orchestras and ONE pianist  devote themselves to this still undiscovered wonderful musical genre.

The communicative powers through its music and the intoxicating atmosphere this group creates on stage has repeatedly been praised by critics and has become a hallmark of the ensemble 4.1.

In addition to the original masterworks for this instrumentation by Wolfgang Amadeus Mozart and Ludwig van Beethoven, the ensemble is devoted to discovering rarely played compositions from the Romantic and Modern periods. After many years of silence, composers like Walther Gieseking, Theodor Verhey, Herrmann Zilcher and Arne Oldberg are again being performed for an enthusiastic public.

The beginnings of the group were overseen and fostered by the renowned Goethe Institute, who assisted with the initial concerts and worldwide tours. Since its inception in 2013, the ensemble 4.1 has already crisscrossed the globe and performed recitals in China, Pakistan, Austria, Germany, Algeria, Canada and the USA, in cities such as Berlin, Istanbul, New York City, Toronto, Ottawa, Karachi, Shanghai and Chengdu. They have appeared with great success at festivals in Denmark and on Malta, as well as at the Kotor Festival in Montenegro.

The requirements have changed. Whoever is playing chamber music today can’t be limited to the rules from decades ago. The expectations regarding the diversity of repertoire have changed, which creates room for ensembles like the Faure Quartet, which has established itself as one of the world’s leading piano quartets within just a few years. Dirk Mommertz (piano), Erika Geldsetzer (violin), Sascha Frömbling (viola) and Konstantin Heidrich (cello) use the opportunities arising from these developments. They discover new sound fields in chamber music and perform compositions outside the mainstream repertoire.

They are visionary in their approach and highly regarded for their experiments and discoveries; be it performances with the NDR Big Band, collaborations with artists like Rufus Wainwright or Sven Helbig, appearances in clubs like the Berghain, Cocoon Club or “Le Poisson Rouge” in New York or TV shows in KIKA or “Rhapsody in School”, getting children excited in chamber music. When they released their album “Pop Songs” in 2009, there was a great deal of buzz in the press and audience. In the following year, the ensemble was awarded the ECHO Classic for their album “classic beyond borders”, their second award after their recording of Brahms’ piano quartets (Chamber Music recording of the year, 2008). Other prizes include the German Music Competition, the ensemble prize from Festspiele Mecklenburg-Vorpommern, international competition and recording awards, Music Prize Duisburg and Brahms prize Schleswig Holstein.

The musicians of the Faure Quartet are pioneers in many ways. After they met during their studies in 1995 in Karlsruhe for the 150th anniversary of Gabriel Faure, they quickly realized, that this combination offered new insights into undiscovered repertoire. In 2006, they signed a contract with Deutsche Gramophone, promoting them to the Champions League of the classic music business. They made highly regarded benchmark-recordings with works by Mozart, Brahms, Mendelssohn and pop songs from Peter Gabriel and Steely Dan as well as works from Mahler and Richard Strauss (Sony Classical). on one album. Currently the quartet is releasing the world’s first-ever recording of Mussorgsky's “Pictures at an Exhibition” and Rachmaninov's “Etudes-Tableaux” in their own arrangements on the Berlin Classics label.

Worldwide tours raise their profile abroad and international masterclasses are part of their work with students. The members teach at the universities of Berlin and Munich. Moreover, they were Artistic Directors of “Festspielfrühling Rügen” and are ‘Quartet in Residence’ at the University of Music Karlsruhe. During their tours, the musicians appear in the world’s most important chamber music venues; including Concertgebouw Amsterdam, Alte Oper Frankfurt, Berlin Philharmonic, Teatro Colon Buenos Aires and Wigmore Hall London. All these mosaics form a unique profile for this defining chamber music ensemble.

Excerpts from the press

"The Faure Quartet members proved just as successful in Brahms' Piano Quartet No. 1 in G minor, a much better-known quantity. Again, the musicians brought both strength and refined lyricism to the work, as with the vivacious lilt to the Intermezzo and a charming insouciance to the movement's coda."
Chicago Classical Review

"The whole performance had a prismatic vigor."
Indianapolis Star

"This was a performance of great finesse and sensitivity."
Register, Napa Valley

"The communication between the four performers was as beautiful to watch as their music was satisfying to hear. This quartet thinks and breathes as one, focused on a singular, clear vision for their music making."
Toronto Star

"By any standards the individual members of the Faure Quartett play extremely well. What is especially impressive, however, is how well they play together and how well balanced is the total ensemble."

“We can now see the Con Brio as the worthy successors of the legendary Beaux-Arts Trio. That says it all!”- Díapason“

Radiant Russian memorials and unforgettable playing...”- BBC Music Magazine

Recognized as one of the world’s finest piano ensembles, the Trio con Brio Copenhagen’s multifaceted members are notably performing artists who tour extensively, but also esteemed recording artists, artistic directors and educators. The Trio appears regularly at the world’s leading venues and concert series, including Carnegie Hall, Lincoln Center, Wigmore Hall, Berlin’s Pierre Boulez-Saal, the Concertgebouw and many more.        

Trio con Brio is a recipient of the Carl Nielsen and Anne Marie Carl-Nielsen Award, one of Denmark’s most prestigious prizes. the trio is a fusion of two overlapping “musical pairs:” two sisters, violinist Soo-Jin Hong and cellist Soo-Kyung Hong are from South Korea, pianist Jens Elvekjaer, Soo-Kyung’s spouse, is from Denmark. Founded at the University of Music and Performing Arts in Vienna in 1999, the trio is now based in Copenhagen, Trio con Brio Copenhagen is recognized for its exceptional musicianship, fresh approach to the core repertoire, adventurous programming and for the commitment to bring music to young people through their highly creative concerts.

The ensemble’s recordings have received continuous critical acclaim. The latest album of Shostakovich and Arensky Trios (Orchid Classics) was a Gramophone “Editor’s Choice” and was singled out by BBC Music Magazine as a “Chamber Choice” of the month. The disc also won the German Record Critics' Award (Preis der deutschen Schallplattenkritik), and was among other winning titles including the Berlin Philharmonic, Frank Peter Zimmermann, and Quatuor Ebène. Their album featuring the complete Beethoven piano trios (Orchid Classics) garnered broad and enthusiastic praise from critics and fans alike. The BBC Music Magazine calling it “a triumph.” The Trio has also recorded the work of leading Scandinavian Composers, such as Per Nørgård, Bent Sørensen and Sven-David Sandström, who have written works for the ensemble.

As visionary artistic directors who are known for their insatiable curiosity, inventive programming and engaging children’s concerts, Trio con Brio Copenhagen plays a vital role in the cultural life of Denmark. They have  collaborated with leading Danish actor Søren Sætter-Lassen on their new musical production of “The Little Prince” set to open at The Royal Danish Theatre. A tour is planned the following year. Trio con Brio Copenhagen serves as artistic directors of the annual festival, Chamber Music at Lundsgaard, and the Hellerup Chamber Music Society in Copenhagen.

Soo-Jin plays an Andrea Guarneri violin, Soo-Kyung plays a Grancino cello, and Jens is Denmark’s first Steinway Artist. Both string players are endorsed by Jargar Strings and Thomastik-Infeld Vienna.

Excerpts from the press

"Trio con Brio Copenhagen has throughout their career been hailed by press and audiences for their 'unique sound and unity of interpretation'"
Frankfurter Allgemeine Zeitung, Germany

"From the first note, Trio con Brio exudes class ... both explosive and exquisitely intimate - aspects that this performance delivers with compelling panache."
The Strad

"Trio con brio de copenhague: formation d’élite… We can now see the Con Brio as the worthy successors of the legendary Beaux-Arts Trio. That says it all!"

"Radiant Russian memorials and unforgettable playing… I won’t forget this disc."

"This is a very impressive release, contrasting Arensky’s full-blown Romanticism with Shostakovich’s more troubled Soviet-era expression. From the start of Shostakovich’s Piano Trio no.1 we are allured by the players’ sheer tonal beauty, not only in the work’s melancholy lyricism but even in its clanging dissonances, which never seem ugly. There’s boundless joy and passion in Arensky’s Piano Trio, and technique to burn from the players beneath the surface. The slow Elegia movement is breathtakingly tender, with the muted violin and cello creating a magical effect"
The Strad - Edward Bhesania

"The lyric inspiration really flows, with the rich but never over-resonant acoustic of the Royal Danish Academy of Music Concert Hall giving space to each player’s special beauty of tone. While I’ve heard performances of Arensky’s work before which didn’t engrave it on the memory, the Copenhagen trio truly make it live. I won’t forget this disc.”
BBC Music Magazine

"Everything adds up to a completely thought-through and deeply felt interpretation… In every way, then, this is an outstanding achievement, and I only hope the disc gets the acclaim it deserves.”

"Here the combination of a Danish pianist and two Korean sisters fascinates again, in the Largo assai ed espressivo of op. 70/1, between whispered conversations and terrifying textures. Three different visions all in one timbre precision. Beethoven, One and Triune."
Scherzo - Pablo L. Rodríguez
