Installed two floors underground in 2025, this site-responsive video and sound work occupied a building flooded by the Rhône and evacuated one year earlier. Subliminal photographs of the flooded zone are embedded in abstract animations. Hydrophone recordings made where the river overflowed its banks merge with atmospheric CO₂ data from 800–2020 translated into sound and theta binaural beats. Below the Surface transforms trauma into memory, fragility and renewal.
