180 Pure Virgin Vinyl LPs in Gatefold Packaging. Although this album marks Thelonious Monk's sole recording as a member of Art Blakey's celebrated Jazz Messengers, the pianist and drummer were very close friends who understood each other well on both a personal and musical level. In fact, Blakey was present on both Monk's first and last studio sessions, spanning a period of 24 years from the 1947 quintet and trio recordings to the last sets taped in London in 1971, when Blakey and Monk were touring with the group called the "Giants of Jazz" (which also included Sonny Stitt, Dizzy Gillespie, Kai Winding and Al McKibbon). With the exception of Johnny Griffin's "Purple Shades", all of the compositions on this album are classic Thelonious Monk tunes.
