Releasing Obsessed on a label other than Sandwell District must have felt strange to Function. However, like "Ember", the US producer's final outing for the now defunct imprint, "Obsessed" is an understated affair. Closer to early Speedy J and Warp's Intelligent Techno series than the austere rhythms of Sandwell, its dreamy synths unravel to reveal a cacophony of bleeps and a lithe rhythm that never quite makes it onto the dance floor. Substance's version starts in a similar vein, but the Berlin producer maintains a wiry, minimal rhythm throughout, which acts as the basis for a gradual shift into grinding metallic riffs. Scuba's SCB edit is the most dance floor friendly track, the snappy, hissing percussion and stacatto, clattering drums underpinning an effective, building filter.
