(WaMu Theater) Here's another USC indoor mega-rave, this time celebrating that most EDM-friendly occasion, St. Patrick's Day (huh?). Whatever, anything will do for an excuse to gather several of the moment's top-grossing club DJs and producers and have them run through their paces before tons of emerald-hued dazzling lights. Speaking of which, headliner Pretty Lights (Colorado producer Derek Vincent Smith) sounds like a one-man revival of '90s Big Beat movement spearheaded by Chemical Brothers and Fatboy Slim, but with less overt funkiness. Other popular beatmakers on the bill include old-school junglists Ed Rush & Optical and High Contrast, trance smoothie BT, and très 'eavy French dubstep/drum 'n' basstards Dirtyphonics. And so many more.
