An aficionado’s household name ever since riding a well-deserved wave of hype in 2008, Burak Sar aka SIS has continued to impress with his instantly recognizable percussive grooves and unmistakable production style. Stepping up for the 99th release on Crosstown Rebels (having previously appeared on the first ever RebelLION) the German producer delivers ambitious four-tracker - the ‘Round Pen EP’. Shakers and bongos open things up on ‘Faces’, before a big, unwavering 4/4 kick enters the floor coupled with a hazy bassline. An evocative sample is used creatively in trademark SIS style and will no doubt have the same devastating effect on the floor. Things then get a little darker with a minimal, almost micro house intro on ‘Unforty’. Spacey pads and a menacing bassline lead the way hypnotically until an organ synth line snaps us out of the trance, giving the track a new perspective. We then dive straight back into some more vocal-led, peak time madness on ‘Miles From Me’. SIS displays his renowned propensity for manipulated vocals, chopping up a blues sample beyond recognition and then releasing the full vocal later on; whist a gratifying combo of warming distortion, elongated reverb tails and echoed stabs ensures that sounds twist and turn for the duration. Finally we return to the deep for ‘Forward Line’, a driving and relentless piece characterised by a slick percussive groove and hypnotic synth lead.
