Recorded in 1964, Jackie McLean's It's Time was only available on CD in the United States as part of a four-disc Mosaic set of his complete Blue Note recordings between 1964-1966. The band here includes trumpeter Charles Tolliver, pianist Herbie Hancock, bassist Cecil McBee, and drummer Roy Haynes. The music was written entirely by either Tolliver or McLean and walks the line between modal post-bop and free jazz.
