Director Michael Mayer has placed his new production of Verdi’s towering tragedy in Las Vegas in 1960—an ideal setting for this eternal conflict of depravity and innocence. In this production, inspired by the antics of the Rat Pack, Piotr Beczala is the womanizing Duke of Mantua, with Željko Lučić as his tragic sidekick, Rigoletto. Diana Damrau is Rigoletto’s daughter—and their victim. Michele Mariotti conducts.
