"Poème électronique" was one of the first comprehensive multimedia works, which consistently used the handling of audio material in architectural space. This work was prepared by a trio of artists Le Corbusier, Edgard Varèse and Iannis Xenakis for the presentation of the Philips company at the World Exhibition in Brussels in 1958. Poème électronique is used in this book as a comprehensive term for a set of artistic acts associated with the Philips pavilion. A particular emphasis is placed on the personality of the solitaire and pioneer of electroacoustic music, Edgard Varèse. The present publication attempts to trace the lines of the development of the three main protagonists intersecting an interpretive framework designed by the aesthetics of contemporary art groups and movements.
