Lead track 'Spirit Module' is perhaps the finest summation of Reif's aesthetic yet: a mixture of bleepy, raw techno that, with its wild vocal samples and wide, 808-driven groove, comes across like a tougher, more modern take on the classic Sheffield/Richard H. Kirk/Robert Gordon sound. Label partner Ken Meier's first outing here as a remixer is a smashing success his version strips things down, keeping most elements of the original intact, but adds a driving, almost double-time metronomic machine rhythm that's aimed squarely at the dancefloor. On the flip, 'Tension' and 'Symmetry Obsession' row the boat further out, with their synapse-frying tones and jagged, randomized sequences reminiscent of Freddy Fresh at his best. All in all, a future classic destined to find favor with adventurous house and techno DJs alike.
