by Scott Yanow Performed as one of eight concerts at the 1989 Montreal Jazz Festival that featured bassist Charlie Haden, this trio set teams Haden with pianist Paul Bley and drummer Paul Motian. Playing adventurous but unclassifiable music that falls between bop and the avant-garde, the trio contributes one original apiece and also interprets four Ornette Coleman tunes and Carla Bley's classic "Ida Lupino." The musical communication between the three masterful players is impressive on this generally introspective set.
