Formerly director of the Ateliers UPIC/CCMIX from 1991 to 2007, Gerard Pape founded the C.L.S.I. (Cercle pour la Libération du Son et de l’Image), an ensemble consisting of composer-performers singing, playing instruments, and computers “live” in 2007.

Monographic CDs of Pape’s music first came out on Mode records in 1992, 1998 and 2006. Another monographic CD of his music came out in 2007 on Iancu Dumitrescu’s label, Edition Modern.

Two new monographic CDs of his music came out in 2015 on Stradivarius Records and Mode Records. A bilingual book of Pape’s texts as well as musicological texts about his work, MusiPoéSci, was published in 2015 by Editions Michel de Maule in Paris.
