[2] It is noted for the appearance of pianists Thelonious Monk and Horace Silver, both playing on the Monk composition "Misterioso".

Monk also plays on his composition "Reflections", while Silver handles the piano duties on all the other tracks.

British singer-songwriter Joe Jackson paid homage to the album when he mimicked the sleeve for his 1984 album Body and Soul.
