The American director Jay Scheib was looking at a bank of monitors inside the Bayreuth Festival Theater on a recent afternoon. He was rehearsing his new production of Wagner’s “Parsifal,” which opens the storied Bayreuth Festival on Tuesday, and as performers circled a large metallic monolith onstage, the screens showed three-dimensional flowers floating through blank space — psychedelic animations that will come to life for audience members who see them with augmented-reality glasses. Through those glasses, Scheib said, the flowers, and other items during the performance, will appear to float through the auditorium. In keeping with the opera’s themes, he added, these moments are meant to provide the audience with “sacred visions” of “a world where wonder still exists.”Scheib’s production is one of the most ambitious, and high-profile, attempts to incorporate augmented reality into opera performance. But it also caps months of tumult at Bayreuth, after plans to outfit nearly 2,000 audience members with the glasses for each performance were downscaled because of an apparent money dispute between the festival’s artistic and financial leadership.
