Opera and Cabaret

Films based on operas are not uncommon. Mozart’s “The Magic Flute,” for example, was adapted for the screen by both Ingmar Bergman, in 1975, and Kenneth Branagh, in 2006. Next up in The Met: Live in HD series is a rarity, an opera based on a film, the source in this case Luis Bunuel’s 1962 “The Exterminating Angel,” the story of a group of upper-class friends who are invited to a mansion for dinner and are inexplicably unable to leave.

The opera, by the British composer Thomas Ades, which The New York Times called “a major event” when it premiered at the 2016 Salzburg Festival, will be simulcast at Guild Hall on Saturday at 1 p.m. Sung in English, the wickedly comic takedown of the rituals of the wealthy is directed by Tom Cairns, the librettist, in collaboration with the composer, who also conducts. Tickets are $22, $20 for members, and $15 for students.

The JDTLab will present “Gutless and Grateful,” Amy Oestreicher’s solo cabaret show about the almost unimaginable sequence of medical traumas she calls her “beautiful detour,” on Tuesday at 7:30 p.m. After developing a blood clot the week before her senior prom, she was rushed to the hospital, where her stomach exploded and both lungs collapsed. Several months in a coma were followed by 27 surgeries that reconstructed her digestive system.

Ms. Oestreicher is an artist, writer, actress, health advocate, and speaker for TEDx and RAINN (the Rape, Abuse, and Incest National Network), and her 70-minute musical autobiography is meant to inspire people to flourish because of, rather than in spite of, challenges. The performance is free, but reservations are encouraged.
