Connecting the best R&B, funk, reggae and hip-hop dance sounds (and the people who love each), THE BRIDGE, which ran from 2004 to 2007, returns to mark a special milestone, the 40th birthday of one of its head DJs, the inimitable Mr. Choc. Best known for his radio work on both Power 106 and K-DAY, Choc also celebrates his 25th year behind the turntables, so his set is sure to show off his intricate, scratch-infused style to the max. DJ Hapa, Dynamix, DJ Shakee and special guest DJ Babu will also be on hand to bring some amazing wax manipulations and selecting skillz to the reunion party, at a brand-new location the promoters call “custom-designed” just for the event. 2324 Cotner Ave., W.L.A. RSVP for discount admission at thebridgepresents.com. Similarly soulful and organic feeling, SPIRIT L.A. celebrates its first anniversary the same night with guests Marques Wyatt (Deep) and Tony Powell (Dirty Dirty House club). Expect rhythmic, uplifting house music amped by live percussion from Erik Rico. The Grand, 943 N. Broadway, Chinatown; universal-rhythm.com. Both clubs, Sat., March 13.
