Born 1948, lives in Biel, Switzerland. Hans Koch has quit his carreer as a recognised classical clarinetist to become one of the most innovative improvising reed-players in Europe. He has been working with everyone from Cecil Taylor to Fred Frith since the eighties. As a composer he has shaped the sound of Koch-Schütz-Studer since the beginning as well as working for radio-plays and film.Since the nineties he has been working with electronics as an extension of the saxes/clarinets as well as with sampling/sequencing. As a reed-player he is always working on his very own vocabulary and sound, which makes him a very unique voice on the actual scene.
