Black History Month kicks off with a bang, a live broadcast of the Metropolitan Opera’s celebrated new production of Porgy and Bess. First performed in 1935, the working-class opera is about the disabled beggar Porgy (Eric Owens) and the much sought-after Bess (Angel Blue), both outsiders in the fictionalized Catfish Row neighborhood of Charlestown, South Carolina. When the show starts Bess is attached to a no-good dockworker named Crown, but then there’s a craps game, a murder, an island getaway, and a hurricane that changes everything. The two-act opera runs about three hours (not including the half-hour intermission). It opened the Met season back in September to rave reviews.
