W Song focuses on underwater sound signals and the phenomenon of echolocation.

Through the prism of her voice, performer Violaine Lochu tries to capture the territorial division and complex interconnections between the various components of the marine world. Her vocabulary resonates with human and non-human sounds - sperm whale clicks, fog horns, sonar beeps, drilling hammers, blue whale songs, and dolphin whistles, creating a cyborg opera involving the body, space, and sound.
