Extremely active from 1972-82, then reformed in 2008, and now entering a new phase of their improvisational journey, the OM quartet of Urs Leimgruber on saxophones, Christy Doran on electric guitar, Bobby Burri on double bass, and Fredy Studer on drums & percussion extend their transformative approach to free improv through what they refer to as "ElectroAcoustiCore".

The remarkable Swiss improvising trio Koch-Schutz-Studer collaborates with NY improvising vocalist artist Shelley Hirsch for an amazing album of voice and electronic and acoustic improvisation with few boundaries and incredible insight.
