Produced by Impulse! A&R director Bob Thiele in 1963, this recording is a major showcase of the talented Charles Mingus as a bassist, pianist and writer. In his 1963 original liner notes, critic-at-large Nat Hentoff said that of all the musicians, it is impossible to remain indifferent to Mingus. This recording more than any other testifies to Hentoff's claim. More so today than in 60's, there is truly only one Mingus.
