This record might be the coolest I've painted on, as far as the record itself. "Rock The Casbah" by The Clash is a 12" 33 1/3 single. Just one song on a side. The way they pressed it is what makes it so cool.
Instead of spacing the grooves like they would on a whole album, they're spread out so the one song takes up the space that 4 or so normally do. What this does is make the grooves really visible.
You can see the music.
