[Intro: deep cavernous drone, subharmonic rumble, wind through stone] [Vocal: single slow breath, no words, formant-shifted] [Sub-bass drop: slow distorted half-time pulse, subharmonic shadow, not aggressive] [Vocal: non-lexical hum, barely present, ancient residue] [Instrumental: tectonic low movement, alien organic texture] [Vocal: long exhale dissolving into cavern reverb] [Outro: sub-bass fading, wind returning, silence]
