This four-CD set has the exact same music as an earlier Mosaic five-LP box, but is highly recommended to those listeners not already possessing the limited-edition set. Trumpeter Clifford Brown is heard on the most significant recordings from the first half of his tragically brief career. Whether co-leading a date with altoist Lou Donaldson, playing as a sideman with trombonist J.J. Johnson, interacting with an all-star group of West Coast players, or jamming with the first (although unofficial) edition of Art Blakey's Jazz Messengers (a two-disc live performance with a quintet that also includes the drummer/leader, Donaldson and pianist Horace Silver), Brown is the main star. Highlights are many, including versions of "Brownie Speaks," Elmo Hope's "De-Dah," "Cherokee," "Get Happy," "Daahoud" and "Joy Spring." The attractive packaging, with its 40 pages of text and many rare pictures, is an added bonus.
