The Polytope de Cluny was an incredible success: its two versions, performed continuously from October 1972 to January 1974, had a total of more than 200,000 spectators. The show took place in the thermal baths at Cluny and was presented with the subtitle "actions of light and sound". The public, lying on the floor, was indulged in a luminous and sonorous debauchery characteristic of Xenakis. The music, with its homonymous title, is often played as electroacoustic music - it uses material from Xenakis's earlier pieces, but also included, for the first time, the sounds of stochastic synthesis. As for the visual performance—made of flashes, laser beams and mirrors, with configurations that are sometimes abstract, sometimes concrete—was entirely computerized and thought to be lost. But the digitization of the Xenakis archives makes it possible, today, to recreate it, a recreation that this seminar will question.
