One of the greatest jazz recordings of all time, Sketches of Spain features Miles with large ensemble arranged and conducted by Gil Evans. Truly a jazz milestone, this album presents Davis and Evans at their musical peak. Miles Davis's impact on jazz is almost incalculable. From his early days as a sideman for Charlie Parker, through his groundbreaking Birth of the Cool sessions, to his stunning small groups of the '50s and '60s, through to his electric renaissance, the trumpeter, bandleader, and composer has left a deep mark on all who came after. He is one of jazz's true giants. Sketches of Spain, though one of Davis's most commercially successful sessions, is also one of his most controversial. Re-teaming with arranger and composer Gil Evans, who played such a pivotal role in Davis's 1949 Birth of the Cool recordings, Davis recorded a series of large group albums beginning in the late '50s, including Porgy and Bess, Miles Ahead, and Quiet Nights. Sketches of Spain, with its emphasis on flamenco, rich orchestrations, and relaxed tempos, is certainly one of Davis's most mellow recordings (he even works out on fluegelhorn), and proved to have broad appeal. To some critics, however, the project was "elevated elevator music." An expanded version of the album, featuring alternative tracks and unreleased material, was issued in 1997 by Columbia Legacy. --Fred Goodman
