Déviation Heat-treated isn't really an aesthetic compromise, so much as an excuse for Fell to do his thing. Across two side-length tracks, fragments of the originals are picked out, isolated and fed through the inimitable Sensate Focus prism, throwing up gorgeous fractal configurations of sound that hint at dance forms before skipping puckishly away into the heat haze. For the most part, then, this is business as usual: finely poised asymmetrical beat patterns rendered with a crisp percussive palette; looped micro-fragments of voice and digi-organ; lush synthetic pads that coil lazily overhead.
Still, there are hints that Fell is working to expand the project's distinctive grammar. He breaks free of the relatively staid structures found on previous singles, opting instead for suite-like constructions: ideas are seeded, blossom and then die away, leaving new ones to grow in their place. And occasional moments of menace interrupt the smoothness of it all, particularly in the latter half of side A, where glassy synth tones build to a baleful, brain-boring peak.
