Sébastien Singer, who has been passionate about chamber music since early childhood, became a natural cellist with the Swiss Piano Trio in 2000. From then on, he was involved in the artistic rise of the ensemble, with which he won successively the 1st prize of the International Competition of Caltanissetta (I), the 1st prize of the International Brahms Competition (A) and the coveted Swiss Ambassador's Award. After sixteen years of international career in over fifty countries on all continents, numerous record releases and hundreds of concerts in halls such as the Wigmore Hall in London, the Tonhalle Zurich, the Victoria Hall in Geneva, the Concert Gebouw in Amsterdam, the Great Hall of the Tchaikovsky Conservatory in Moscow and many others, Sébastien Singer decided in 2016 to end his activity in the Swiss Piano Trio. Together with the wonderful musician and virtuoso guitarist André Fischer - a friend and constant companion with whom he has played in duo since his youth - Sébastien Singer is continuously expanding the repertoire of original works, arrangements and transcriptions for guitar and cello. With a catalogue of works ranging from Bach to contemporary works, the duo singer & fischer is today one of the unmissable ensembles of this genre (www.singerfischer.ch). Other musical personalities with whom he shares a complicity that goes beyond the scope of interpretation include the pianist Brigitte Meyer, the organist Guy Bovet and the violinist Daniel Zisman. In addition to these regular collaborations, Sébastien Singer has played with violinist Pierre Amoyal, violists Paul Neubauer and Steven Dann, clarinettist James Campbell, pianists Paul Coker, Marc Pantillon, Gerardo Vila and many other exceptional musicians. Since Sébastien Singer is convinced that every decent musician must take an interest in contemporary music, he has been playing in the Streiff Quartet since 2021. Before that, he was solo cellist with the Nouvel Ensemble Contemporain de la Chaux-de-Fonds for around ten years. Within this framework, he was involved in the premiere of numerous works and worked closely with composers such as G. Aperghis, F. Hoch, J. Levine, M. Wettstein, J. Wildberger, J. Wyttenbach and others. Sébastien Singer has made recordings for the labels SwissPan, Audite, Claves, Acanthus Music, Grammont and Stradivarius, as well as for Espace 2, DRS 2, RTSI, ORF, Vietnam National TV, Australia ABC, Radio Television Hongkong, Venezuela State TV, CBC Canada, etc.
