a club night held at a small indoor venue in aarau, built around a surround sound performance format developed by the producer waio over more than a decade of technical research. the setup uses multi-speaker spatial audio to move sound around the room rather than projecting it from a single stage, and the configuration is expanded with each edition. attendance is capped at 250, and the space is dressed with visual art by calaquendi art and jan artista.

this is the fourth edition of the format in switzerland, following appearances in 2019 and across 2024 and 2025. waio is a psytrance producer with an extensive international touring history, and the event sits at the intersection of psy-rooted electronic music and an explicitly technical approach to sound design and playback.
