“Installations” was a work for fourteen dancers, made with the use of the LifeForms software. According to Cunningham, his idea for the dance came from a video installation by the company’s resident filmmaker, Elliot Caplan, based on the film “Beach Birds for Camera.” For this new dance, the décor was another video installation by Caplan, on which film images of the dancers were projected in groupings devised by Cunningham before the choreography of the dance was made. These images “prompted,” in Cunningham’s word, some of those in the dance itself. The music was by the Seattle-based German composer, Trimpin. Caplan collaborated with Suzanne Gallo on the costumes, and with Kelly Atallah on the lighting.
