Altoist Jackie McLean has recorded so many fine albums throughout his career, particularly in the '60s for Blue Note, that Mosaic could have reissued his complete output without any loss of quality. This four-CD limited-edition box set contains six complete LPs worth of material plus one "new" alternate take. The music (which also features trumpeters Charles Tolliver and Lee Morgan; pianists Herbie Hancock, Larry Willis, and Harold Mabern, vibraphonist Bobby Hutcherson, bassists Cecil McBee, Bob Cranshaw, Larry Ridley, Herbie Lewis, and Don Moore, drummers Roy Haynes, Billy Higgins, Clifford Jarvis, Jack DeJohnette, and Billy Higgins) is explorative (showing the influence of Ornette Coleman) but without totally disregarding McLean's bebop roots. The performances straddle the boundaries between advanced hard, post and free bop jazz with Jackie McLean consistently emerging as the main star. His solos are consistently exciting, full of unexpected twists and turns.
