To celebrate the fact that Deborah Voigt and Ben Heppner are finally singing together, the Met is streaming Tristan und Isolde live. Go to the Met home page and click the obvious graphic. You need RealPlayer (sorry).
Peter Gelb just told the audience that DVo & HeppB are both singing - hooray! The originally-scheduled Brangaene seems to be ill, however, so first-cast member Michelle DeYoung is taking the performance.
