For avid readers of PCL Linkdump you'd be caught in a bubble within a timewarp if you have not heard of the amazing freeform radio station WFMU.
Recently posted to YouTube is a 3-part short documentary on "MAC", host of the radio show, the Antique Phonograph Music Program. The show appear bi-weekly, every Tuesday, at 7PM Eastern Time.
Besides programming a radio show providing flashbacks of music close to a century old, there is a wonderful archive, The Internet Museum of Flexi/Cardboard/Oddity Records (that has been on the web for years).
Presented here is the wonderful documentary on MAC, his records, radio show and to fellow collectors of music from a bygone era I believe you will delight in these short videos.
