en Altadefinizione. Déserts was created to accompany a live performance of the work of avant-garde composer Edgard Varèse (1885-1965). The Ensemble Modern, a contemporary music group based in Frankfurt, commissioned Viola to create a visual score for Varèse's Déserts after discovering notes by the composer referring to an unrealized image component of his composition. The resulting film/videotape was produced with the European television stations ZDF/Arte. In October 1994 Viola's Déserts premiered in a live performance in Vienna with conductor Peter Eötvös and the Ensemble Modern.
