PLAN A: MRK1, Mr. Biggs, Head$hake, Austin Speed @ El Dorado. A producer from Manchester whose name is a nod to KRS-One, MRK1 makes dubstep and grime (a subgenre of U.K. hip-hop) with blunted beats and a mid-tempo, reggae-tinged chug. Get here early for "Dub Dorado" resident DJs Mr. Biggs, Head$hake and Austin Speed, the guys responsible for this extra-heavy, twice-monthly dubstep night. PLAN B: LA Riots, TJR @ Voyeur. A DJ duo with a hipster sensibility, LA Riots meld elements of techno, house and drum 'n' bass into remixes of artists as diverse as indie-techno brats Crystal Castles and Dutch dance overlord Tisto, as well as into their own party-hardy tracks. PLAN C: The Bloodflowers @ Bar Pink. If electro ain't your thing, then The Bloodflowers are just what you need-no-frills rock 'n' roll la Queens of the Stone Age. BACKUP PLAN: DJ Gabe Vega, Hyena, DJ Man Cat, Coda Collins, Lesands, DJ Leif, Hoopnectar, Maystar, Trevor Dean @ Belly Up.
