It's Bootie's Bay To Breakers Pre-Party! Live on stage at 11 PM, Cookie Dough presents the Monster Drag Show, an unbelievable, non-stop, multi-queen, drag mashup spectacular on the Main Stage! No breaks, no emcee, just the best of twisted San Francisco drag! Also in the Main Room, mashup DJs Mykill, Tripp, and Lex will keep you dancing all night long, limbering your legs for the long Bay To Breakers run the next day!

Upstairs, the Monster Drag Show's DJ MC2, along with Guy Ruben, take over the Lounge for the Monster Electro-House Party, while in Above DNA, Glitterazzi welcomes you to the "Darkside of EDM," as DJs Meikee Magnetic and Mixtress Shizaam take you on a journey of sight and sound with their brand of EDM, electro, house, mashups, and trap. And in the Dazzle Room, Ya Mamma's Basement brings the party you threw when your mom was out of town ... the one you hoped she didn't come home early to catch you throwing! DJs Myster C and Mr. Washington will get you bumpin' and grindin' on the dance floor, as they highlight the connection between hip-hop, funk, old-school, and R&B

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.
