Variations VII was John Cage’s contribution to these encounters. Cage was an acquaintance of Marshall McLuhan and Buckminster Fuller, so he was aware of the advances being made in telecommunications and their impact on society and art. For the event, organised by Billy Kluver, he performed Variations VII, in which he used radio waves and telephone lines onstage to produce real-time transmission of sounds from outside the venue. In the piece, Cage gave a special place to shadow theatre. Projected onto the huge white canvases that surrounded the performers were the shadows of the musicians and the objects around them, converting the sound manipulation into a theatrical event, and subverting the monochrome painting as a screen. The work is Opus 7 in the Variations series (1958-1967), the key element of which is the search for uncertainty in musical composition, and which anticipates some aspects of his later series Theatre Pieces.
