If you’re in San Francisco this weekend, there’s a doozy of a mini-film festival at the Roxie Theater. “This Must Be The Place: Post-Punk Tribes 1978-1982” is a series of short films documenting the regional post-punk scenes in the UK, France, Los Angeles/Orange County, San Francisco, Pittsburgh, New York City, and elsewhere. SFMOMA’s Gina Basso and Roxie programmer Mike Keegan have curated the most provocative and rarely scene visual documents of that profoundly important period in the history of DIY and underground culture. Check out the full schedule over at the Roxie Theater site. Worth noting is that the killer song in the trailer above is Liquid Liquid‘s “Cavern” (1983), with the bassline that became the basis for Grandmaster Melle Mel’s “White Lines (Don’t Do It).”
