Opera Marathon at Guild Hall

The Met: Live in HD will kick off its season with an encore screening of a new production of Wagner’s “Tristan und Isolde,” which will be shown on Saturday at noon at Guild Hall in East Hampton. The production will feature an outstanding cast of Wagnerians: Nina Stemme as Isolde, Stuart Skelton as Tristan, Ekaterina Gubanova as Brangane, and René Pape as King Marke. 

The running time of 5 hours, 15 minutes will include multiple intermissions. Tickets are $22, $20 for members, $15 for students.

To further enrich the experience of the opera, the screening will be preceded at 11 a.m. by a breakfast reception and lecture by Mark Mangini, the music director of the Choral Society of the Hamptons. Titled “Brahms vs. Wagner: Composers in Conflict,” the talk will feature a discussion of the German Romantics’ famed controversy. Tickets to the breakfast and lecture are $50, $48 for members. They do not include tickets to the opera.

In other happenings at Guild Hall, David Crane, a war crimes prosecutor, founder of the Syrian Accountability Project, and a Syracuse University law professor, will present a talk titled “Seeking Justice and Accountability in Syria” on Sunday at 2 p.m. Dr. Crane will share the story of a Syrian defector who delivered evidence of torture and mass murder to the international judicial system. A wine and cheese reception will precede the free talk at 1 p.m.

JDTLab will present a free staged reading of “Dancing on Ice,” a play by Janet Sarno and Anita Keal, on Tuesday evening at 7:30. The play is the story of Charlie, a sailor on leave who has just tried and failed to lose his virginity, and Julie, a prostitute who has had her night’s earnings taken by some policemen. While Julie fearfully awaits her pimp, she and Charlie gradually warm to each other by way of their love of dance. Christopher Imbrosciano, Mary Murphy, and Paul Pakler star; Ms. Sarno directs.
