Billy Roisz, since the late 1990s, dealt intensively with video and sound. Her work focuses on the links and gaps between visual and auditive perception. Roisz questions the interaction between sound and image, the interchangeability or unity of the electromagnetic signal in the generating machines which creates image or sound. The realisation of her experiments takes place in live performances, single screen works and audiovisual installations, solo or in collaboration with musicians of experimental music and noise as well as composed new and old music, dance and theatre.
