The best of Tristan— and, indeed, of all Wagner — is, of course, the orchestra and its leadership, and in this regard the news continues great. Conlon is all over the place, to our great benefit. His orchestra continues slightly undersize and, by the standards of Wagner's own demands, under-rehearsed, but he has gotten it to play at top capacity, and it sounded great on Saturday. Before all that, he was up in a public space, chatting up Tristan and Wagner in general until about 10 minutes before downbeat; he has an important article in the program, and more writing on his Web site. At the end he drew the biggest cheers, which was only right.
