Nico Muhly and Paul Appleby on Two Boys at the Met

Composer Nico Muhly discusses his opera Two Boys, which made its American debut at the Metropolitan Opera in October. He’s joined by Paul Appleby, who plays Brian, the lead character. The opera is based on real events 10 years ago in Manchester, England, and tells the story of a 16-year-old boy who nearly killed a younger boy — egged on, the attacker claimed, by mysterious people he encountered in an Internet chat room.
