Duke Ellington and I share a birthday today, so to celebrate, here's a look at how records (remember them?) were made in the 1930s with Duke Ellington's Orchestra performing Oh Babe, Maybe Someday with Ivie Anderson. "Electrically engraved with the world's finest entertainment!".
Early footage of Duke Ellington's band in the studio recording a record. details the process of vinyl manufacturing in the 1930s.
Happy Birthday Duke!
