La légende d'Eer is a powerful 7-channel electro-acoustic composition which Xenakis created to be played in Le Diatope, a curvaceous architectural construction designed by the composer, together with a visual component including laser lights. This multi-media work was composed for the opening of the Centre Georges Pompidou in Paris, where it was performed for three months and seen by thousands of people. <br><br>La Légende d'Eer is shown with a film by Bruno Rastoin, comprised of 350 stills made during the original performance of the work at the Diatope. These stunning images have been woven together into a film and are the only visual documentation made of the historic event.
