Le Corbusier - um poema em concreto

The Philips Pavilion at the Brussels World's Fair in 1958 was designed in large part by Iannis Xenakis, at the time one of Le Corbusier's architectural assistants. The program in the pavilion during the World's Fair consisted of Edgard Varèse' Poème Electronique played through 400 loudspeakers, projected images and colored lights created by Le Corbusier, and Iannis Xenakis' Concrète PH played as an interlude between shows.

As Varèse later described it, the sound followed paths through the loudspeaker arrays, and groups of speakers were used to create effects such as reverberation. He said, "I heard my music literally projected into space."
