The 2016-2017 Metropolitan Opera’s Live-in-HD season of broadcasts from Lincoln Center to the Strand Theatre, 345 Main St., begins Saturday, Oct. 8, at noon with a new production of Wagner’s “Tristan und Isolde.” An encore broadcast is scheduled for Tuesday, Oct. 18, at noon.

“Tristan und Isolde” will be conducted by Sir Simon Rattle in his first Live-in-HD performance. Nina Stemme stars as Isolde, a touchstone role she has sung with major opera companies around the world. Her Tristan is Australian heldentenor Stuart Skelton, who sang Siegmund in the Met’s Ring cycle in 2013.

The cast also includes Ekaterina Gubanova as Brangäne and Evgeny Nikitin as Kurwenal (both in Met role debuts); with René Pape reprising King Marke, a role he has sung to acclaim in three previous Met seasons. The staging, by Mariusz Treliński (who directed the 2015 Met double bill of “Iolanta” and “Bluebeard’s Castle”) is a co-production with the Festival Hall Baden-Baden, Teatr Wielki – Polish National Opera and China National Centre for the Performing Arts, Beijing.

“Tristan und Isolde” is sung in German, with English subtitles, and runs an estimated four hours and 47 minutes. Tickets are $27; $15 for students younger than 19 and college students with ID, available on the website or by calling the Strand. Encore show tickets, available day-of-show, are $23/$5.
