Conch of Rust

[A single conch shell blown into a contact mic. Natural sound, no effects.]

[That same blow, pitch-shifted down a fifth.] [Then layered with itself. Then five more shells, all blown in dissonant harmony.]

[A heartbeat enters. Not a drum machine. A kick drum with the beater pressed against the head, struck softly, then amplified.]

[The shells fade. The heartbeat continues for two more beats. Then cuts.]
