LONG BEACH, Calif. — Bill Viola, a video artist who combined with director Peter Sellars on a groundbreaking production of Wagner's ''Tristan und Isolde'' originally seen in Los Angeles, Paris and New York, has died at age 73.
Viola died Friday at his home in Long Beach of Alzheimer's disease, his website announced.
What was called ''The Tristan Project'' opened in concert form at Los Angeles' Walt Disney Concert Hall in 2004, premiered on stage at the Paris Opéra the following year and was presented in concert at Lincoln Center's Avery Fisher Hall in 2007.
His staging has been revived several times in Paris, as recently as 2023, and versions have been presented in Helsinki; Kobe, Japan; London; Madrid; Rotterdam, Netherlands; St. Petersburg, Russia; Stockholm; Tokyo; and Toronto. Videos were exhibited at New York's James Cohan gallery in 2007.
''I hope that the audience will leave the theater having a deeper understanding of the nature of our short time here on Earth and the importance and power of love and any kind of relationship we're in really with the things and people in the world,'' Viola said in a 2013 interview with the Canadian Opera Company.
While singers performed on the stage, a huge video showed images of individuals, water and candles and fire that ran from grainy gray to high-definition color. His technique included Viola filming in Vermont woods for a week alone with a camcorder; to building a waterfall on a soundstage and lowering an actor on a wire, then using the video in reverse during the performance to make the actor appear to rise; to a crew of 70 in an airplane hangar with a 90-foot pool of water and 25-foot-high wall of flame.
''A defining moment in nearly 140 years of continual staging of an opera that transformed (and continues to influence) music more than any other single work,'' Los Angeles Times critic Mark Swed wrote after a 2022 revival at Disney Hall.
During the Liebestod, the love-death that concludes the opera, Tristan's body starts to bubble and he dissolves like Alka-Seltzer as he rises.
