The producers of this show said they sought to recreate the recording art as it stood in 1929, but in one respect they "cheated." Instead of recording on wax masters, they used lacquer masters, which were introduced into recording in the mid-1930's. Lacquer had three advantages over wax: it sounded better, it was more durable and the masters could be played back immediately. A wax master had to go through elaborate metallurgical processing before it could be made into a playable records, and artists in the wax-master days couldn't hear their recordings until about three weeks after they were made, when the record companies sent them test pressings.
