This Sunday, it’s the Folsom Street Fair, which San Franciscans will know isn’t your average street party. “San Francisco has served – and continues to serve – as the global epicenter of sexual liberation for the adult alternative lifestyle community,” write fair organizers, and this year marks the event’s 25th anniversary.

There are two stages bands at the street fest this year, including Bay Bridged interviewees Excuses for Skipping (interview here) and Von Iva (interview here), headliners The Presets, Shiny Toy Guns, Berlin (!) and The English Beat (!), and a ton of others.
