Originally recorded on February 6, 1966 at the Van Gelder Studio, Englewood Cliffs, New Jersey. Happenings was vibraphonist Bobby Hutcherson's fourth Blue Note release as a leader. Where it's predecessors Dialouge and Components were packed with challenging Avant-bop, Happenings instead brings things down a notch. With pianist Herbie Hancock, drummer Joe Chambers, and bassist Bob Cranshaw on board, Hutcherson keeps the tone fairly light, performing his original compositions (the exception is Hancock's "Maiden Voyage") with a mellow, swinging style that emphasizes modal exploration. The performances are all top-notch, and the album still weighs in as one of the best in Hutcherson's fine catalogue.
