Skream has always reserved his deadliest club material for the Skreamizm series of EPs. Volume six, the first addition to the series since 2009, proves no exception. His attention might have been divided between exploring a range of styles on 2010's Outside The Box (TEMPA 016CD) album, but all seven tracks here stay locked, hard, to the demands of the dancefloor. Broader in its sonic range than any other Skreamizm so far, the range of sounds within this sixth volume in the series reflects dubstep's growing status over the last couple of years. It encompasses the sort of crushing, big-room club tracks his sets have become increasingly known for. "Xmas Day Swagger" is metallic and bristly, and the shuddering "Indistinct"'s intensity is cleverly offset by tiny melodic flourishes and fragments of female vocal. Both "Abstruse" and "Snarled" match their titles perfectly, the latter in particular casting robotic half-step in sleek, predatory shapes. The most startling moments, though, are those that depart from straight-up club form: a characteristically acerbic vocal from Trim on "Tweedle Dee Tweedle DUMB!"; and "FNKONOMIKA," where Skream continues to explore the sort of stripped-back, twilight drum 'n' bass pioneered by friend and collaborator dBridge. Dubstep at the moment finds itself in something of a scattered state -- blame it on Skrillex. Skream's music, though, remains closely linked both to his own history and to the genre's roots. It's refreshing to hear a producer making tracks for larger dancefloors that retain something of the subtlety and nuance of the past.
