This was a CD insert that was supposed to be on an aborted SALLY SKULL retrospective called “Skullduggery”. By aborted, I mean it never came out, and that 1994-97 Sally Skull stuff is still nearly impossible to find unless you drop a few bucks on one of their two 45s via Discogs.
Of course, you can get the entire backstory on this excellent raw garage/artpunk band via Dynamite Hemorrhage #1 fanzine, which has an interview w/ Claire & Saskia from the band.
