Record Making With Duke Ellington (1937)

This promotional short for Irving Mills' short-lived Master and Variety labels not only gives us a glimpse of Ellington and his band in the actual Master/Variety studios (as opposed to a soundstage set), but is one of the very few film accounts of how records were recorded, plated and pressed in the long-ago age of analog, shellac and 78 rpm. Narration is provided by pioneer radio announcer Alois Havrilla.
