Dark cinematic dubstep at 140 BPM, built from sub-heavy reese bass, metallic FM growls, and a tense D-minor string motif. Start with granular piano fragments, distant choir pads, reverse impacts, and filtered noise, then slam into syncopated half-time drums: huge kick, snappy snare, and triplet hi-hat rolls. Automate distortion, bitcrushing, and cavernous reverb for an oppressive, unresolved atmosphere.
