Para que gosta de Ópera...

Last week, just about every major museum and cultural institution in NYC announced that it would temporarily close to try to limit the spread of coronavirus. That included the Metropolitan Opera, who said that all performances have been canceled through at least March 31st. Now, these places are starting to think about ways to adapt to our radically different cultural landscape—and the Met Opera will begin streaming encore presentations from their award-winning Live in HD series on the company website for the duration of the closure.

All “Nightly Met Opera Streams” will begin at 7:30 p.m. and will remain available via the homepage of metopera.org for 20 hours.

“We’d like to provide some grand opera solace to opera lovers in these extraordinarily difficult times,” said Met General Manager Peter Gelb. “Every night, we’ll be offering a different complete operatic gem from our collection of HD presentations from the past 14 years.” Lincoln Center has suspended all public performances and screenings through the month of March, as well.

Here's the schedule for this week:

Monday, March 16 – Bizet’s Carmen (Conducted by Yannick Nézet-Séguin, starring Elīna Garanča and Roberto Alagna. Transmitted live on January 16, 2010.)

Tuesday, March 17 – Puccini’s La Bohème (Conducted by Nicola Luisotti, starring Angela Gheorghiu and Ramón Vargas. Transmitted live on April 5, 2008.)

Wednesday, March 18 – Verdi’s Il Trovatore (Conducted by Marco Armiliato, starring Anna Netrebko, Dolora Zajick, Yonghoon Lee, and Dmitri Hvorostovsky. Transmitted live on October 3, 2015.)

Thursday, March 19 – Verdi’s La Traviata (Conducted by Yannick Nézet-Séguin, starring Diana Damrau, Juan Diego Flórez, and Quinn Kelsey. Transmitted live on December 15, 2018.)

Friday, March 20 – Donizetti’s La Fille du Régiment (Conducted by Marco Armiliato, starring Natalie Dessay and Juan Diego Flórez. Transmitted live on April 26, 2008.)

Saturday, March 21 – Donizetti’s Lucia di Lammermoor (Conducted by Marco Armiliato, starring Anna Netrebko, Piotr Beczała, and Mariusz Kwiecien. Transmitted live on February 7, 2009.)
