At first the French Jean-Marc Foltz studied physics before going to the conservatory in Strasbourg. Subsequently, from '88, the clarinettist focused on contemporary music as soloist in various ensembles and on jazz in the jazztet of guitarist Bernard Struber. More and more he lost himself in jazz and improvised music, especially when he started playing with musicians like Raymond Boni, Joe McPhee and Gaguik Mouradian. Foltz, who has a very good reputation in France, now forms a trio with pianist Stéphan Oliva and bassist Bruno Chevillon (featured on the live album Cette Opacité). Foltz also forms duos with these two musicians separately. Next to that he tours with the Bill Carrothers' septet Armistice. Two years ago Foltz started his own trio for clarinet, bass and drums. He is now working on a CD.
