The long-running association of Chicago legends, trombonist George Lewis and saxophonist Roscoe Mitchell, are recorded live at CTM Festival at HAU Hebbel am Ufer, in Berlin in 2018, accompanied by Lewis' laptop adding a third voice that responds and generates textural and rhythmic accompaniment in response to the playing of both improvisers; impressive and exotic.

Multi-instrumentalist Roscoe Mitchell explores sparse, exploratory settings in this studio recording featuring tenor and soprano saxophones, whistles, bells, percussion, and woodwinds, joined in various duos and trios by bassist Richard Davis, drummer Vincent Davis, violinist Vartan Manoogian, and Steve Sylvester on bullroarer, the ensemble shaping spacious improvisations that investigate texture, overtone resonance, and the shifting architecture of sound.
