His user name is Davismv. He worked at Kmart for ten years. That’s all I know. But he saved the tapes that were played on the Kmart PA and now he’s uploaded them to the Internet Archive. Most of them are about 90 minutes each and there are about 50, spanning the early 1990s. Obviously I have not listened to them all, but it’s a lot of easy listening, PA announcements, etc. They are weirdly glorious.
