This is a timely intersection for a search I've been doing for archives of the Quiet Storm shows of the 90s from Power 99 FM in Philly. At the start of my search I didn't realize how ephemeral radio was treated. Growing up I listened to tapes of Abbott and Costello, The Shadow, and dozens of other shows. I just assumed there were recordings of everything. I found hundreds of KCMU and WFMU shows I recorded from live streams, when I wasn't living near enough to get the terrestrial signal. And the odd LPFM / pirate broadcasts. It might be time to build an archival WARK.fm
