Booing directors has become standard at Bayreuth, but the dissenters were only a small segment for Jay Scheib’s “Parsifal” this year, dominated by AR glasses and a theme of global energy collapse.

Even more remarkable, the tenor Andreas Schager sang the title roles in “Siegfried” on Saturday and “Parsifal” on Sunday, and then Siegfried in “Götterdämmerung” on Monday — all with clarion enthusiasm.
