These 66 songs not only represent Ellington's artistic apex, but perhaps reflect the greatest creative period by any single artist in jazz history. Ellington had already made a lasting impression on jazz by 1940, but adding writer/arranger Billy Strayhorn, young bassist Jimmy Blanton, and tenor great Ben Webster brought the band to extraordinary new heights. The new blood boosted a roster already touting Johnny Hodges, Cootie Williams (replaced by Ray Nance), Rex Stewart, Juan Tizol, and Barney Bigard. The set list reveals masterpiece after masterpiece: Ellington's "Cotton Tail," "Never No Lament," "All Too Soon," "In a Mellotone," "Warm Valley," "I Got It Bad," and "Sentimental Lady" plus Strayhorn's "Chelsea Bridge" and "Take the 'A' Train" offer a mere taste of the treasures within. --Marc Greilsamer
