And lo, when dubstep finally “breaks” the American mainstream, it will wear the cherubic face of an ex-screamo singer from Southern California (Revelation 7:9). That baby face belongs to 23-year old producer Skrillex, born Sonny Moore, formerly of Ross Robinson/Epitaph footnote From First to Last, who graced the cover of Spin, sporting an asymmetrical haircut and multi-colored nail-polish, for last month’s (long overdue) “dance issue.” Beyond the magazine-ready profile, and remixes of Lady Gaga and Korn, what Skrillex brings to American dubstep is Michael Bay-outsized production values: not only in terms of ultra-glossy (though putatively “dark”) sound design, but also with a massive projection-mapped stage setup, in which a motion-capture bodysuit–ed Moore gives life to a giant video avatar. Expect to behold a great multitude, which no man could number, at the WaMu tonight, standing before the lamb-like Skrillex and his 3D Throne, clothed in neon spandex and glow sticks in their hands. Repent. With 12th Planet, Two Fresh, Nadastrom. ERIC GRANDY
