Bristol-based American James Ginzberg has masqueraded as 30Hz for the past few years, producing crowd pleasing breakbeat numbers and putting them out on his Vertical Sound label. Given his involvement in the founding of seminal dubstep label Tectonic, however, his interest in fare less likely to hit number one on Beatport has been there to see for anyone who cared to look. His new project, Emptyset, probes a sound most easily described as Monolake gone to Bristol. The first two EPs, released on the Future Days imprint, have so far failed quite to hit the mark, but nevertheless forged a distinctive tone consisting of sparse and monochromatic minimal informed by the ever ebullient voice of Bristol bass.
