"In Tonband, meaning 'tape' as in tape-recorder, the acoustic sounds played by the percussionists are filtered, transformed, and distorted in real-time to become otherworldly and unnatural. These sound manipulations are controlled live by the pianists on two full-size MIDI keyboards, with each key activating a different process for nearly limitless possibilities. The percussionists generate all of the acoustic sounds in the piece, which are then passed through the keyboards as the pianists twist and alter them, all in the same instant."
