On March 4, DJs Richie Panic and Corey Sizemore will celebrate ten years of debauchery with a special, anniversary edition of their recurring dance party, Lights Down Low, at the Mezzanine in San Francisco. Longtime pillars of the city’s club scene, the pair started LDL as a small function at the now-defunct Tenderloin club 222 Hyde (which the San Francisco Bay Guardian once nicknamed a “rave cave”). Since then, it has expanded into an influential West Coast brand. In addition to booking internationally recognized electronic music artists, such as Simian Mobile Disco and Disclosure, Panic and Sizemore have thrown editions of the event at various clubs in Los Angeles and at the hugely popular festivals Coachella and South by Southwest. The upcoming anniversary party will feature deep house purveyors Skream and Jamie Jones. If you miss that show, there will be another ten-year anniversary celebration on April 20 at Public Works in San Francisco featuring 2ManyDJs from Belgium.
