by Scott Yanow Although best known for leading quartets that feature top young guitarists (his alumni include Larry Coryell, Pat Metheny and John Scofield), vibraphonist Gary Burton has actually headed different types of combos since at least 1978. On this ECM CD reissue, Burton is joined by altoist Jim Odgren, longtime bassist Steve Swallow and drummer Mike Hyman. The repertoire is stronger and less introverted than usual, featuring songs by Chick Corea, Mick Goodrick, Carla Bley ("Reactionary Tango"), Billy Strayhorn ("Isfahan") and Oscar Levant ("Blame It on My Youth"). Swinging sections alternate with more thoughtful pieces, resulting in a particularly well-rounded set.
