While more cerebral than emotive, this live set is a frenzied demonstration of what four virtuosic musicians sound like when they give in to the intuitive whims of collective improvisation. Even when playing a composition, this quartet will stretch and mutate the melody into every possible pattern without ever playing it directly. The group interplay is often bombastic and can be overwhelming, but thankfully they vary the dynamics through mellower sections, as well as solo and duo pieces.
