Concepts of community, dialog, sharing and transmission, or "recontre", are the linking ideas between these four works commissioned of Montreal composer and wind player Jean Derome, developed for four Quebec ensembles, these pieces combine contemporary and improvisational forms, the scores shaped by constraints from the combinatorial mathematics of Marin Mersenne.

Ensemble Supermusique, Montreal's premiere open-minded improvising ensemble, here led by saxophonist & vocalist Joane Hetu and conducted by percussionist Danielle Palardy Roger, present a live concert of graphic scores dating back to 1920, with works from Fred Frith (Stone, Brick, Glass, Wood, Wire), Luigi Russolo, Maxime Daigneault, Emilie Girard-Charest & Anestis Logothetis.
