TechnoPop
No, not the latest Moby song. "TechnoPop" is an excellent series being run on NPR's Morning Edition Fridays that looks at the history of technology and popular music. It touches on the consumer experience and music-making in the studio, from the player piano to multi-track recording to (next week) the Internet Age and do-it-yourself recording.
It's a quite good series. Check out the archives. (You'll need the free RealOne Player to hear the stories.)
