Bassist William Parker, already a mainstay of the New York free jazz scene for two decades, finally took on a leadership role with this quartet featuring alto saxophonist Rob Brown, pianist Cooper-Moore, and drummer Susie Ibarra. Between 1995 and 1998 they recorded four albums for various labels; this double disc gathers live performances from four shows. The eight tracks are bluesy and abstract in a post-Mingus style, lasting between 12 and 25 minutes without ever feeling aimless or indulgent.
