SKREAM AT THE FILLMORE: A veteran of the dubstep scene before it even had a name, Ollie Jones (aka Skream) brought grime’s far more engaging and intricate sibling out of the shadows in 2005 with “Midnight Request Line.” An unlikely club and blogger sensation, Skream’s calling card married minimalist Space Invaders blips and beeps to experimental garage production that recalls the hypnogogic unease of avant-garde pranksters The Residents. Seven years on, Skream is busy deconstructing the very stylistic devices he helped create. Still remaining true to dubstep’s clammy, juddering roots, he now grafts the formerly underground style to shiny, sparkly pop. True, this marriage of light and dark can produce a mongrel like the plastic trance of current buzz cut “Anticipate,” but dubstep unvarnished is by nature self-limiting, and as one of its key creators, Skream had to take the sound somewhere. Why not the dance-pop mainstream?
