Prompt

Dark ambient with a slow, suspended pulse and irregular low-end swells; verse-like sections stay nearly empty with cold drones and distant room tone, 
pre-chorus moments thicken into spectral vocal fragments, and the main swell lands with sudden pipe organ stabs and ruined-hall reverb, 
A few reversed risers, stone-scrape textures, and cavernous delays drift between changes, Wide, gothic, murky mix with a close, oppressive low midrange
