Presently known as The Fucking Champs, once upon a time, way back in the early 90s, they were known simply as The Champs. Tim Green of Nation of Ulysses fame was not yet in the band, and they released this tape, Music for Films About Rock. Includes a killer cover of Motley Crüe's "Merry Go Round", too.
Ripped from my own cassette. I'm guessing there aren't too many copies of this still around. Other weirder, more obscure cassettes to come soon.
Enjoy. Link in comments.
