Not only does this CD feature a "new quartet," but it was the beginning of Gary Burton's longtime association with ECM. In general, Burton's ECM dates were more introverted and laidback than his more diverse Atlantics, but they always had their moments of interest. On this set, the vibraphonist, guitarist Mick (then known as Michael) Goodrick, bassist Abraham Laboriel and drummer Harry Blazer perform numbers by Chick Corea ("Open Your Eyes, You Can Fly"), Keith Jarrett ("Coral'), Gordon Beck, Carla Bley and Mike Gibbs, in addition to Burton's "Brownout." Intriguing if not essential music.
