Editor's info:
Constantly digging into his musical philosophy, Roscoe Mitchell invites us here to enter by listening to the creation of this unique environment, unique because created by interaction between hic and nunc (and “once and for all” thanks to the recording) with his partners, therefore literally un-heard.
