Gensai Hasegawa（長谷川 現斎） — Discography

Minimal Feedback / Structural Noise / Technoise - last updated, 09-01-2026

I work with unstable systems, minimal feedback, and structural ambiguity. My practice seeks to capture psychological states such as disorientation, anxiety, and dissociation. Rather than pursuing traditional musicality, I focus on texture, silence, and the instability of sound itself.
