riddim dubstep, 140 BPM half-time pulse, sparse kick and snare with clipped offbeat hats, tightly gated metallic mid-bass phrases answering in short syncopated bursts, sub bass locked to a simple two-note motif, brief tension risers and abrupt stop-start drop sections, minimal arrangement with clear space between hits, gritty controlled distortion, punchy low end, dry close drums and wide restrained effects
