 The first performance of the combined orchestral and tape sound composition came as part of an ORTF broadcast concert, between pieces by Mozart and Tchaikovsky and received a hostile reaction.Le Corbusier was commissioned by Philips to present a pavilion at the 1958 World Fair and insisted (against the sponsors' resistance) on working with Varèse, who developed his "Poème électronique" for the venue, where it was heard by an estimated two million people.Using 400 speakers separated throughout the interior, Varèse created a sound and space installation geared towards experiencing sound as it moves through space.
