In 1965, with help from Robert Rauschenberg, Billy Klüver sought the expertise of engineers at Bell Laboratories (Murray Hills, New Jersey, U.S.) to participate in an interdisciplinary project blending avant-garde theatre, dance and new technologies. For the project, 10 artists (John Cage, Lucinda Childs, Öyvind Fahlström, Alex Hay, Deborah Hay, Steve Paxton, Yvonne Rainer, Robert Rauschenberg, David Tudor and Robert Whitman) each created an original performance. They were then paired with the engineers, who helped produce the technical components used on stage by the participants (dancers, actors, musicians). "9 Evenings: Theatre and Engineering" was to be presented as part of the Stockholm Festival of Art and Technology in 1966. But when the festival's American program was cancelled, Billy Klüver moved the event to the 69th Regiment Armory (New York), where it ran from October 13 to 23, 1966.
