That’s what the New Ballet in San Jose is offering for a performance of Sleeping Beauty this weekend: a group of patrons will sit together in the balcony, dial into a conference call, and listen on earbuds to live commentary as well as background on the ballet and interviews with dancers. Says company director Dalia Rawson, “It’s a bit radical, … but I think context and additional information will enhance the experience, just as it does when watching football or the Olympics.”
