shawn o’ sullivan marks return to shifteds avian imprint with a four track ep under his 400ppm alias. following on from 2013s non nocere, the new yorker pairs trademark stripped back drum programming with heady, warping drones and frenetic sequencing. even at full throttle, careful attention to detail lends the productions a degree of musicality oft missing from contemporary techno. subtle nods to idm feature, and references to o sullivans work with katie o sullivan as further reductions remain in the form of spacious verb and fluid atmospherics, but the focus is undeniably on the dance floor. printed inner and outer sleeve... black vinyl.
