lieu commun is a speculative fiction in constant transformation, in which only species with queer and non-monogamous behaviors have survived the Collapse. In this post-apocalyptic ecosystem, multiple entities coexist within a constructed, dark, and subterranean environment. They attempt to attune to one another through their own languages, developing new forms of relationship, communication, and interdependence. The interactive soundscape accompanies their evolution: it influences these entities, and they influence it in return by vocalizing.
