This most unusual Duke Ellington record includes two selections featuring nine symphonic percussionists on timpani, vibes, marimbas, and xylophones. Dizzy Gillespie makes a historic appearance with Ellington's orchestra on "U.M.M.G." (a meeting that should have been repeated often but sadly never was), Jimmy Rushing (Count Basie's former vocalist) sings "Hello Little Girl," and both Johnny Hodges ("All of Me") and Paul Gonsalves ("Ready Go!") have chances to blow.
