Makin' the Changes features altoist Jackie McLean in two different settings. On three selections -- a rollicking "Bean and the Boys," an up-tempo "I Never Knew" and "I Hear a Rhapsody" -- McLean teams up with pianist Mal Waldron in a quartet with bassist Arthur Phipps and drummer Art Taylor. The other three numbers ("What's New," " "Chasin' the Bird" and McLean's original "Jackie's Ghost") have more of a jam session feel, and feature McLean in a sextet with trumpeter Webster Young, trombonist Curtis Fuller, pianist Gil Coggins, bassist Paul Chambers and drummer Louis Hayes. In general, the hard bop music is swinging and fairly advanced, a step above the usual jam sessions of the time.
