This feature-length documentary chronicles the life and playful methods of Dutch pianist and composer Misha Mengelberg, a significant figure in post-WWII European Jazz and free improvisation. Archival footage, rehearsal / performance sequences and interviews with both Mengelberg (the "godfather of Dutch improvised music") and key collaborators provide a clear insight in Mengelberg's original way of thinking and way of working.
