Originally released in 1973. Featuring Monk with Al McKibbon (bass) and Art Blakey (drums). Includes a version of "Misterioso" which "illustrates the marvelous musical partnership between Monk and Art Blakey who, while the composer develops the double-tempo implications of his 8-to-the-bar theme, not only prompts him but, without being in the least obdurate, gradually engages him in a perfect dialogue.
