Post‑punk / Darkwave, 105 BPM, 4/4. Mood: melancholic, cold, mysterious, urban isolation, eerie. Raspy male vocal (solemn in Verse 1 → intense in Verse 2 → raw in Verse 3 → near breaking point in Verse 4), ethereal female vocal (whisper‑like) in Final Chorus. Instruments: drum machine (mechanical hi‑hat, snare on beats 2&4), bass synth drone, sub‑bass rumble (30 Hz), clean guitar with delay, distorted guitar in choruses, atmospheric synth pads, sparse piano, reverse arpeggios. Effects: distant sirens (fade in/out), wind (rises and howls), clock ticking/running, footsteps, door creak, whisper, bitcrush.
