Boesch studied with Messiaen and also within the Groupe de Recherches Musicales. In 1968 he took a position as director of the Lausanne Conservatory, but he left in 1972 to pursue his compositional career. He wrote for film and stage as well as instrumental, electronic music, and mixed-media pieces. He took part in collective compositions with the Paris group GERM and the Berne group Neue Horizonte as a player and improvisational planner. Boesch collaborated with a sculptor in 1972 in a project involving tape music and visual art. ~ Lynn Vought, Rovi
