Critical Values


Critical Values captures electroacoustic improvisation at its most essential — raw, direct, organic, charged with tension. This recording documents a first encounter between three seasoned improvisers, Jonas Kocher and the duo Bertoncini/Lehn. It has been preserved exactly as it happened: unedited, unaltered, split across two tracks.

Album available on Bandcamp or by email at contact@bruit-asso.org, for CHF 15.– including shipping.
