Since the beginning of making records there were devices available to record onto records by using a lathe cutting machine.  These machines were marketed to professional music engineers and also consumers. Using a specific cutting head you would in real time, groove the record with playback audio. Recently I had the chance to visit www.lathecuts.com a CO-OP lathe cutting facility in Tucson, Arizona.  Here multiple artists offer different takes on production, training or demonstration of the complex skill in making lathe cut records.
