This is one of the most soulful, driving recordings I have ever heard, bar none. I first owned a copy of Mosaic upon being mercifully turned on to it by a couple of hip peers back in 1981. I went looking for it again recently upon having a jazz revival of sorts, and was thrilled to see it being offered in CD reissue. Folks, this is epic music not only in terms of Art Blakey and his many personnel configurations through time but in terms of the history of jazz music itself in America. Everyone should own a copy of this album at some point to hear the sheer propulsion, emotional penetration, waterfalling chords, bountiful melodic content, utterly towering musical abilities of the sidemen as well as Buhaina (Blakey) himself, and the overall presence of soul in this recording. The first reviewer must have had cotton swabs in his ears. This set of Messengers with the legendary Wayne Shorter of Weather Report, trumpeter Freddie Hubbard (Red Clay), Cedar Walton and Curtis Fuller is as good a jazz group as can be found anywhere in the history of the art and this particular musical session was one of Blakey's finest. Get it and enjoy.
