World Expo '70

Expo '70 was a World's Fair held in Suita, Osaka, Japan between March 15 and September 13, 1970.

E.A.T. (Experiments in Art and Technology) carried out a project to design and program the Pepsi Pavilion. Four core artists, Robert Breer initiated the design, which finally brought together 63 U.S. and Japanese artists, engineers, and scientists. (...)

David Tudor designed the sound system with 32 inputs, sound modulation systems, and 37 speakers arranged in a rhombic grid on the dome behind the mirror. Sound could be moved at varying speeds linearly across the dome and in circles around the dome, or it could be shifted abruptly from any one speaker to any other speaker. The lights and sound could either be pre-programmed or controlled in real time by the artists from a console at one side of the dome. The artists conceived of this space as performance area that could be used by many visiting artists during Expo '70.
