A rare example of a movie which uses jazz both organically and dramatically, with stunning effect, and with a slight plot that provides a background for the first appearance of Duke Ellington on film. On screen is Duke Ellington and his Cotton Club Orchestra: Arthur Whetsol, Freddy Jenkins, Cootie Williams, trumpets; Barney Bigard, Johnny Hodges, Harry Carney, reeds; Joe Nanton, trombone; Fred Guy, banjo; Wellman Braud, bass; Sonny Greer, percussion; Ellington, piano; with the Hall Johnson Choir and Fredi Washington. Musical numbers: "Black and tan fantasy" by James 'Bubber' Miley, Duke Ellington; "The Duke steps out", "Black beauty", "Cotton Club stomp", "Hot feet", "Same train", by Duke Ellington.
