Jammin' the Blues is a 1944 short film in which several prominent jazz musicians got together for a rare filmed jam session. It features Lester Young, Red Callender, Harry Edison, Marlowe Morris, Sid Catlett, Barney Kessel, Joe Jones, John Simmons, Illinois Jacquet, Marie Bryant, Archie Savage and Garland Finney. For some, this is their only known appearance in a theatrical film. Barney Kessel is the only white performer in the film. He was seated in the shadows to shade his skin, and for closeups, his hands were stained with berry juice. Lindy Hop legends Archie Savage and Marie Bryant do the Lindy Hop (Jitterbug) on this footage. Directed by Gjon Mili and selected for preservation in the United States National Film Registry.
