A hybrid project based in Bristol, England, Emptyset is grimy and cryptic, driven from within by the region’s body-buzzing bass culture, inspired from without by minimal techno innovations in Berlin and Detroit. The 10 short tracks—the longest clocks in at just over six minutes—seem like sketches of more epic versions and may initially disappoint. But repeated listenings of pieces like “Over,” “Beyond,” and “Awake” reveal a gift for clever sequencing and complex textures; and the hard-charging “Completely Gone,” where the duo compresses all its influences into a rolling ball of evil thunder, is designed to slay the dancefloor, pure and simple.
