Originally released in 1961, Out of the Cool is widely considered to be Evans's masterpiece, on par with Duke Ellington in terms of orchestration, and essential listening for any jazz fan. Evans had spent the previous few years working with Miles Davis on such acclaimed works as Miles Ahead, Porgy and Bess, and Sketches of Spain (DOG 904LP), a collaboration that proved to be extremely enriching for both artists. This LP was Evans's first post-Miles recording, and the album's title, Out of the Cool, is an obvious nod to that fact (a play on Davis's own Birth of the Cool). The album showcases two particularly significant Evans compositions: The groundbreaking "La Nevada" and "Sunken Treasure." Features Elvin Jones on drums; Charlie Persip on percussion; Ron Carter on bass; Ray Crawford on guitar; a horn section of Ray Beckinstein, Budd Johnson, and Eddie Cane on saxophones; trombonists Jimmy Knepper, Keg Johnson, and Tony Studd; Johnny Coles and Phil Sunkel on trumpets; Bill Barber on tuba; and Bob Tricarico on flute, bassoon, and piccolo.
