We’re very interested in Wagner’s Ring cycle—you know, academically. But sitting through 16 hours of opera? Honey, Bobby Jr. is expecting us at the Riverkeeper benefit tomorrow, and we have to squeeze in a manicure! We’d much rather get briefed on what we really need to know at today’s panel discussion at the Tribeca Film Festival, featuring luminaries like soprano Deborah Voigt, tenor Jay Hunter Morris and Metropolitan Opera general manager Peter Gelb. The whole thing’s in support of Wagner’s Dream, a documentary on the Ring cycle (we thought they already made one, and called it Lord of the Rings!).

SVA Theater, 333 West 23rd Street, 6 p.m. Tickets and information can be found at http://tribecafilm.org.
