Tight, narrow spaces translated into sound — Airshaft moves through constricted passages of filtered drone and muffled resonance, as though the music itself has to find a route through the building. Kesambi works with pressure and release, letting tones build against invisible walls before finding small openings to exhale through. The textures feel structural, load-bearing, more concrete than cloud. It's one of the more genuinely claustrophobic entries in the drone catalog — not uncomfortable, but close.
