Lucky Milinder's band plays, Sister Rosetta Tharpe sings, and dancers do the Lindy Hop in this soundie.
Soundies were short films, about three minutes in length. The were meant to be played on a machine called a Mills Panoram, a video jukebox that was typically to be found in bars, lounges, and similar venues. You put a dime in and got a performance from the ten on the machine. The movies would be changed weekly, and from 1940 through 1946, Mills and other companies produced more than two thousand soundies.
Sister Rosetta's singing led the way from gospel to rhythm & blues, and thus to rock & roll, and this one was so engaging that I found myself tapping my feet during the solo solo.
