I play forgotten 45 RPM vinyl records for your free-form listening pleasure—sometimes on KOOP Radio 91.7 FM in Austin [KOOP.org] and sometimes here on this website. The needle glides along the grooves of the record and provides a more physical connection to the music, so expect to hear a little surface noise.
Check out the Podcast Archives listed below to hear some past shows.
BTW, I don't make any personal gains by doing this. It's purely a narcissistic pursuit and a way for me to show off my cleverness while (hopefully) exposing you to some new/old music you probably missed the first time around. Please don't sue me.
