Heads down, eyes closed and get marching because this is another muscular outing from the Portuguese techno label HAYES. It is a 40th, in fact, so by now the label knows how to unearth the most compelling of sounds and that's just what Norbak serves up here: these are bangers steeped in traditionalism with hulking great drums and layers of percussion and synth texture peeling off as the drums march on. Heavy, hypnotic, and with a dark funk at their core, they're perfect weapons for a wide range of strobe-lit club settings.
