 As a young man he earned money by selling his paintings , exhibiting some of his works at the Lyon Gallery – L <unk> <unk> , and by playing in a band called Mystère IV . While he studied at the Lycée Michelet , his mother arranged for him to take lessons in harmony , counterpoint and fugue with Jeannine <unk> of the Conservatoire de Paris . In 1967 he played guitar in a band called The <unk> , who appear in the film Des <unk> et des filles . He mixed instruments including the electric guitar and the flute , and tape effects and other sounds . More experimentation followed in 1968 , when he began to use tape loops , radios and other electronic devices , but joining the Groupe de Recherches Musicales ( GRM ) in 1969 , then under the direction of Pierre Schaeffer ( " father " of musique concrète ) , proved hugely influential .
