Although the Hamilton Scalpel 12" has been released on a new imprint called Concrete Cabin, it’s billed as a “covert transmission from the outskirts of Neurealm,” an easter egg that recalls the mystery that characterized much of the early rave era. Nostalgic? Absolutely. But the music here is also raucous, full of energy, and, most importantly, fun. Furthermore, it sounds fresh, especially when its furiously shuddering percussion is held up against the rigid, identikit house and techno that’s being turned out in bulk these days.
