According to the liner notes and all contemporary databases with proven reliability, this is the only extant video footage of Jim Shepard's jaw-dropping band Vertical Slit in any form. Running around 30 minutes or so, filmmaker David Kerr's footage is very much a DIY affair, steeped in gloriously primitive, narrative experimentalism. The single free-form jam explodes visually into a psychedelic miasma, and there are dystopian cameos from all your favorite monsters.
