I had asked the musician François de Roubaix to write some music that he would like, to which I would later put images. His father gave me the cassette where François had recorded some music that didn't inspire me at all. Then one day, it was a flash of lightning: liquid crystals, the latest version of Yves Bouligand with whom I had shot miles of film on this subject, from the first to the last image, without editing, the correspondence burst forth... Cosmic coincidence.
