We work in the media of video, installation (video, sound, light, photography), performance and music. The various fields of these different media and themes influence and interact with each other. We work as a pair, alone, in changing formations and with Les Reines Prochaines. We are inspired by the physical and philosophical, the everyday, the mythological, the absurd, as well as cultural history.
