Le Corbusier's A/V Architecture
Interactive Architecture has a nice report (with links to video including the one above as well as other links) to Le Corbusier's poém électronique, extensively audio-visual-enhanced architectural design for the Philip's Company pavilion at the 1958 World's Fair in Brussels.
The whole project was initiated and directed by Le Corbusier, who also created and/or selected the images for the audiovisual show, with the organized sound composed by Edgar Varèse, and the stunning surfaces of the building designed by Iannis Xenakis. The result was a ground breaking immersive environment, since the space of the Pavilion hosted the audio and the visual materials as integral parts of the architectural design.
