Cunningham, 80, whose innovative choreography has been expanding audiences' expectations about dance for more than 50 years, is reticent about connecting the dots. "The only relationship between the virtual and real dancers is the one you make for yourself," he says, comparing the experience of watching Biped to channel surfing. But that may be precisely the point, according to Roger Copeland, author of an upcoming book on the choreographer. Copeland believes that Biped, like much of Cunningham's recent work, is about how to focus your attention in a world full of distractions. "It's a model for a very progressive society, where different components are able to exist side by side without encroaching on one another." That may sound like a pipe dream, but in Cunningham's inspired rendition, it's an irresistible one.
