Duke Ellington: The Blanton-Webster Band (RCA Bluebird)

The Blanton–Webster Band is a compilation album that combines the master takes of all the recordings by Duke Ellington's Orchestra during the years of 1940 to 1942, involving bassist Jimmy Blanton and tenor saxophonist Ben Webster. The recordings were originally made for RCA Victor during what many critics regard as the Ellington orchestra's golden period. The three CDs contain many numbers which were to become classics, and the arrangements (by Ellington and Billy Strayhorn) were frequently inventive and innovative.
