In the summer of 1985, a contemporary art exhibition about a northern aurora was held in Montréal. Thirty Canadian artists participated in the event, among them Michael Snow, Irene Whittome, Rober Racine and Geneviève Cadieux. Their work focused on the relationship between man and his environment. René Blouin and Normand Thériault attempt to clarify the goals of this exhibition. Presented by the Centre international d'art contemporain.
