While some of us weren't looking, guitars became obsolete. Everybody else was over at Stereo Live. The spacious discotheque at 6400 Richmond — once home to the legendary Club 6400, whose alumni still hold reunion nights — has actually been booking some of the world's top DJs for a few years now. Remixer-turned-superstar David Guetta played in November 2009 when it was still called Planeta Bar-Rio, and trance overlord Paul Oakenfold split an October 2010 bill with Scottish wunderkind Calvin Harris. Then everything exploded, EDM (electronic dance music) and its grimier cousin dubstep came crashing into the mainstream with the strength of Guetta or Oakenfold's brain-busting beats, and Stereo Live found itself in the catbird seat, upgrading the sound and light systems to world-class status and effectively becoming a self-contained operation. After several months of simply producing shows at the venue, Houston EDM promoters Nightculture bought Stereo Live this past May, a move that has already paid off in a revolving-door succession of top talent (Rusko, Porter Robinson, Flux Pavilion) and all but ensures the venue will keep ruling Houston's EDM roost for the foreseeable future.
