Hollow Ground strips everything back to skin. No metal, no synth — just frame drum, hand drum, and fingertip texture, pitched through D♭ Major and left to breathe at 72 BPM.

The piece moves through four phases: a single grounding tone (Invocation), a second voice answering it (Emergence), a drift into overlapping, phasing loops that dissolve rhythm into pure resonance (Transfiguration), and a return to stillness — changed by what came before (Return).

Part of the ongoing Percussion Ambient project: rhythm becoming breath, sound becoming environment.
