Nightlife: Sisterz of the Underground return, Forward SF celebrates a decade, Lexington Club's queer quinceneara, more
SUPER EGO Like many of the great, oldish-school Bay Area hip-hop party collectives, the Sisterz of the Underground core crew has skedaddled — founder Sarah Smalls to LA, creative director Traci P. and organizer Crykit to Las Vegas — following their fortunes to other, perhaps fresher climes. But just like those spectacular b-girl (and -boy) cypher dance circles that have been popping up on finer San Francisco floors of late, the Sisterz are returning, hopefully bringing more of that fly feeling back with them.
A huge Sisterz of the Underground 10th Anniversary Celebration on Sat/31 (sisterzunderground.eventbrite.com ) includes not just a dazzling nighttime party at Public Works  with music by Kid Sister, DJ Shortee, Butterscotch, La Femme Deadly Venoms, Jeanine Da Feen, Green B, Pony P, and more, plus a gallery show of all-female artists, nail art, vendor fair, live painting, and a one-on-one female all-styles dance battle — but also afternoon production tech and dance workshops and a panel discussion about female empowerment and multiculturalism at CellSpace . The Bay is going to get some phenomenal femme in its face, and not a moment too soon OK?
Talking with the Sisterz is a trip — see my full interview on our SFBG Noise blog  — with nostalgic name-drops like storied rap and turntablism venue Justice League, the Extra Credit Kru dance battlers (still in effect), graffiti artist Arouz, emcee Inchant, and Def Ed, the incredible education and empowerment program the Sisterz started that reached schools in six counties in the Bay Area before it was disbanded a couple years ago. The general Sisterz network itself is still slamming, with chapters up and down the West Coast, as well as in New Mexico and Brazil.
And the Sisterz still aren't shy about expressing themselves. When asked about the state of hip-hop, Traci P says, perhaps with a certain super-hyped Bay Area MC in mind, "There is less and less attention paid to substance and more to image and look. Half of these girls can't even perform live and are in a sense disposable because they have no stage presence. Just a pretty face with flashy clothes and jewelry. At a time when everything seems so fabricated, it's essential that people be exposed to the roots of the music and the culture." Werrrd.
I caught this UK house wunderkind last year in Berlin at the awesome Tresor club — he played a pumping, expansive set that eventually set off for deeper currents, intricate grooves ride over each other for long periods and innovative technology put into the service of the steamy atmosphere rather than just being "showy." And he's cute.

Another 10-year banger — this one for adorably talented Adnan Sharif's Forward tech-house collective, bringing in an absolutely bonkers lineup to move us into the next. Deep and wiggy Clockwork from Milan co-headlines with Seattle smart-techno fave Pezzner, plus Nikola Baytala, the No Way Back crew, and a Silent Disco space out side with Star Kommand and more.

Time flies when you're a flaming hot lesbian! Can it be 15 years already since the proudly dive-y Lex threw open its doors to the gorgeously rough-and-tumble dykes of the Mission and their humble admirers (like yours truly)? Oh hell yes. Congratulate owner Lila and crew on keeping one of the few lesbars in homocity open, with filthy music, smokin' go-gos, kinky quinceanera shenanigans, and lipstick-obliterating drink specials.
Sat/31, 9pm, free. Lexington Club, 3464 19th St., SF. www.lexingtonclub.com
