With only one collaboration (alongside fellow DMZ stalwart SGT Pokes under the name ASBO, also for Tectonic) seeing light of day in the last three and a half years, it really has been a long time since dubstep pioneer and producer extraordinaire Loefah ventured out on wax. Responsible for originating the half-step beat in dubstep that came to dominate so much of the scene - with groundbreaking early titles such as ‘Horror Show’, ‘System’ and ‘Ruffige’ - Loefah’s beats always had huge impact on the dancefloor as well as in the studios of other beat-makers, caught by the power of his sound. More recently he’s become predominately focused on his genre challenging DJ sets as well as running his hugely successful Swamp 81 imprint, so this rare studio excursion with Tectonic label boss Pinch is a treat for all to behold. ‘Broken’ starts with a single delaying hat splash as swirling white noise rises from beneath with gale force strength. This relatively gentle moment is soon disturbed by the menacing sound of a tearing bass hit - a twisted sound layered in weighted sub power. Tense pads with distorted edges add to the build before everything pulls out to silence allowing a perfectly timed drop. In comes the full weight of bass as a pounding 808-style rhythm drops - complete with head cracking snares and swung hats - as the main bass sound punches through, ‘Broken’ embarks on a master class in minimal effectiveness. An unmissable collaborative effort between two studio heavyweights, and just how dubstep is meant to sound. Flip for an equally exciting joint effort from Pinch and rising UK Funky and Rinse FM star Roska. Nominated by DJ Mag for the prized title of Producer Of The Year in 2010, Roska is known more for his 130bpm funky productions but this collaboration takes the tempo up to to 140bpm for an exercise in rhythmical maximality - a frantic but rolling conga workout session. Meticulous drum programing is layered with dark reverbed sonics, spooky pads and a gut wren
