In CO_SONIC 38,144 km², a poetic reflection and AI-powered sound landscape, artist Robertina Šebjanič explores the story of coexistence of species and lifeforms through an observation of a river as one entity. The 4DSOUND adaptation for Tribeca Festival integrates the sounds of the Hudson River and bustling New York streets, blending them with the sonic presence of the more-than-human voices of natural and AI-generated entities from the Ljubljanica River, and the Atlantic Ocean.
