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.

A balance between composition and improvisation is sought in this album by The Ensemble Pierre Labbe that is a also a fusion of avant-garde jazz and classical music.
