KMRU & Aho Ssan collaborate at the intersection of atmosphere and impact, shaping music that lingers on thresholds: between silence and rupture, stillness and force. KMRU’s practice is rooted in field recording and long-form spatial composition, while Aho Ssan approaches sound as a philosophical and sculptural assemblage, forged through custom digital instruments and dense electronic pressure.

Their paths converged through a commission from Berlin Atonal – Metabolic Rift exhibition resulting in Limen, first developed in 2021 and released in 2022 via Subtext. Rather than blending their approaches seamlessly, the work foregrounds friction, a mirrored tension between beauty and destruction, where environmental textures are bent into sharp forms and digital intensity dissolves into drifting acoustic space. Limen has since been performed internationally as an AV live set with visuals by Ali Demirel, at festivals including Berlin Atonal, MIRA Festival, Le Guess Who? and WOS festival.

In 2024, the duo presented their new piece Subtle Reclaim at PRÉSENCES électronique 20 for the GRM acousmonium, and continued their sonic research during the Sonic Acts Spatial Sound Residency in 2025. There, they developed a new commissioned work, Still – Fold, which premiered at the Sonic Acts Biennale in 2026.

KMRU and Aho Ssan focus on the physical and perceptual dimensions of listening and composition. Their works unfold as slow transformations, moving from near-inaudible detail to overwhelming sonic mass, inviting audiences into a zone where sound is not only heard but felt. Space itself becomes an instrument, activated through volume and resonance, imprinting introspective depths onto the listener’s body and environment.
