An experimental staging of Richard Wagner's "Der Ring des Nibelungen" at the 150th anniversary Bayreuth Festival, which utilized artificial intelligence to generate scenery, was met with boos and whistles from a portion of the audience.

The production, titled "10010110"—150 in binary—and subtitled "From Myth to Code," aimed to depict the history of the four-opera cycle using AI to integrate images. The concept was developed by curator Marcus Lobbes with Nils Corte and dramaturge Andri Hardmeier, who fed approximately 1,000 images from previous Bayreuth productions into AI models. Stable Diffusion was employed to start each act with scenery designed in 1876 by Gotthold Brückner and Max Brückner, based on sketches by Josef Hoffmann, with subsequent images selected based on text and music.

During the 14 1/2-hour performance, which spanned four nights, singers were positioned between two large screens displaying the AI-generated visuals. The intention, according to Lobbes, was not to produce a cohesive drama but to serve as an experiment. "We always communicated that it’s an experiment, it’s not stage-directed," Lobbes stated.

Following the concluding opera, "Götterdämmerung," conductor Christian Thielemann and the cast received a lengthy ovation, which was interspersed with approximately 30 seconds of audible disapproval when the production team appeared. This reaction echoes historical precedents at the Bayreuth Festival, where initial public criticism of innovative stagings, such as Patrice Chéreau's 1976 production, has sometimes given way to widespread acclaim in later years.

Katharina Wagner, the composer's great-granddaughter and festival director, approached Lobbes in February 2023 to create an AI-driven Ring Cycle for the sesquicentennial. The production involved coders dividing Wagner's work into segments and inputting images to custom-built computers. The singers, including Michael Volle as Wotan, Camilla Nylund as Brünnhilde, and Klaus Florian Vogt as Siegfried, performed in elaborate, shimmering costumes designed by Pia Maria Mackert.

The AI projections evolved with the narrative, at times incorporating unexpected imagery. An image of Theodor Herzl appeared during "Das Rheingold," and one of Adolf Hitler during "Die Walküre." A sign reading "Sorry, no gas today" was projected during "Siegfried." Hardmeier explained that the AI was programmed to select images reflecting what it determined to be the main political topics of each year over the 150-year span.

Original plans for the 2026 festival included performances of the final 10 of Wagner's 13 operas, alongside the debut of "Rienzi." However, budget cuts led to the cancellation of four operas and the addition of two more Ring Cycle productions. The AI Ring was initially planned for a single performance but was expanded due to these scheduling changes.

The singers had limited rehearsal time, with only one nine-hour session over a four-day period. "I would wish that with a certain openness people will find some interesting correlations and will see things that maybe others don't see," Hardmeier commented, expressing hope for "fruitful irritation" rather than confusion among the audience.

The festival also featured a performance of Beethoven's Ninth Symphony, a piece with historical ties to Bayreuth, and a speech by Michel Friedman addressing Wagner's antisemitism and his family's historical connections to the Nazi party. Separately, a production of "Rienzi" updated to a post-modern dystopian setting received extended applause.
