It's Bootie's annual Pre-Folsom Street Fair Party, with plenty of sexy mashups and fetish-tinged fun to go around. Dress up in your fetishwear finest or come as you are! At 11 PM, Bootie's live mashup rock band Smash-Up Derby takes the stage for a sexed-up, fetish/leather-themed set, while fetish faux queen Vesper Synd dominates the Midnight Mashup Show!

Resident DJs A Plus D will be spinning the songs that will have you whipping across the dance floor, while upstairs, it's a West Coast Bootie battle in Above DNA, with DJ Shyboy representing Bootie LA, and DJ Freddy, King of Pants standing up for Bootie Seattle! Plus, Brass Tax takes over the Lounge with their signature delirious sound that continues to tear the roof off at their monthly rager in the Mission! Get your fetish on!

Launched in 2003 by San Francisco DJ duo A Plus D, Bootie was the first club night dedicated solely to the then-burgeoning artform of the bootleg mashup -- and is now the biggest mashup event in the world, with regular parties in several cities on four continents. Voted "Best Club Night" for the past eight years, Bootie celebrates pop culture both past and present, keeping your brain guessing and body dancing with creative song combinations. Mixing and matching every musical genre, era, and style into one big dance party, it's a place where everyone is welcome. And with free mashup CDs given away like candy, Bootie provides the soundtrack for the A.D.D. generation.
