For decades, Tanja Tetzlaff has been one of the most influential musicians of her generation, both as soloist and chamber musician. Her playing is characterized by a uniquely fine yet powerful and nuanced sound, which always goes hand in hand with cultivated musicality. Tanja Tetzlaff’s trademark is her extraordinarily broad repertoire and her desire for new, groundbreaking concert formats.
In April 2021, Tanja Tetzlaff became the first scholarship holder to be awarded the highly endowed Glenn Gould Bach Fellowship of the city of Weimar. She now has the opportunity to realize a two-year film project relating Bach’s famous cello suites to nature and climate change issues: Suites4Nature / Suites for a Wounded World.
Tanja Tetzlaff is a founding member of the Tetzlaff Quartet (Christian Tetzlaff, Elisabeth Kufferath, and Hanna Weinmeister). She plays a cello by Giovanni Baptista Guadagnini from 1776.

In recent years, Norwegian pianist Gunilla Süssmann has been reaping steadily increasing acclaim and has become a much sought-after artist on an international level. Her virtuosity, combined with strong sensitivity and imagination, is highly praised, and her thoroughly personal, passionate interpretations forge a unique bond with audiences and critics. She has performed in venues such as Concertgebouw Amsterdam, Wigmore Hall, the Louvre, and Festspielhaus Baden-Baden, and is a popular guest at major chamber music festivals in Norway and across Europe. The English Chamber Orchestra, the Bournemouth Symphony Orchestra, the Oslo Philharmonic, the WDR Cologne and the Staatskapelle Weimar are amongst the many orchestras with whom she has played. Chamber music holds a special place in her heart, and the core of that devotion is her 12-year collaboration with cellist Tanja Tetzlaff. Critics describe their symbiotic playing as magical, and the duo has recorded two CDs on the Avi label.

“One of the most brilliant and inquisitive artists of the new generation”, said the New York Times of Christian Tetzlaff, one of today’s most highly demanded soloists on stages all over the world. As at home in the classical and romantic repertoire as in contemporary music, Christian Tetzlaff sets standards with his interpretations of the violin concertos of Beethoven, Brahms and Tchaikovsky as well as Berg, Schönberg, Shostakovich and Ligeti. He is particularly well-known for his incomparable performances of the Bach Solo Sonatas and Partitas. In 2005 he was chosen by Musical America as “Instrumentalist of the Year”. He frequently played recitals with Leif Ove Andsnes and Lars Vogt. As a soloist and chamber musician he has performed in all international musical centres, including amongst others New York’s Carnegie Hall and Lincoln Centre, Concertgebouw Amsterdam, Vienna’s Konzerthaus and Musikverein, and in London, Paris, Berlin and Munich.
