Lionel Marchetti was born in Lyon, France in 1967. His interest in music resides in the qualities of sound. He is one of a handful of artists who in the mid-to-late 1990s took electroacoustic music out of academic studios and into the free improvisation ring. A scholar who worked at the CFMI (Lyon) and GRM (Paris) studios and published a book on acousmatic composer Michel Chion, Marchetti developed a set-up of microphones and loudspeakers he uses on stage along with tape recorders, prepared CDs, motors and radios. He often refers to his "instruments" as an "electroacoustic contraption". His live work with Jérôme Noetinger found echoes in the approach of Swiss and Austrian abstractionists like Voice Crack, Günter Müller, and Werner Dafeldecker, but Marchetti is mostly active in France, performing regularly at the club Les Instants Chavirés and at the festival Musique Action. His studio work encompasses sound collage and academic electroacoustics, although the level of poetry and refusal of genre boundaries in his music puts him closer to Kristoff K. Roll and Luc Ferrari than Pierre Henry or Bernard Parmegiani.
