Tenor Richard Croft is inching backward up a 70-degree incline, while singing, on the stage of New York’s Metropolitan Opera. One of a dozen computers parked on tables in the nearly empty auditorium controls an interactive projector that makes flames appear to flicker at his feet. Behind the steep surface that juts high above Croft’s head, stagehands grip a cable attached to his belt, trying to keep any slack out of the line as he moves, fly-like, on the wall.
