ABSTRACT
In the frantically busy year of 1978, during which Le Diatope and Polytope de Mycènes were both mounted and the Unité Polygogique Informatique de CEMAMu computer completed, and in addition to travels to North America, Mexico, Crete, Greece, and two weeks of summer courses at the Centre Acanthes in Aix-en-Provence, Xenakis completed just two instrumental works.
