Simon Keenlyside smolders dangerously in the title role of Mozart’s version of the legend of Don Juan, creating a vivid portrait of a man who is a law unto himself, and all the more dangerous for his eternally seductive allure. Adam Plachetka is his occasionally unruly servant Leporello. It’s when Giovanni tangles with Donna Anna (Hibla Gerzmava) that things start to unravel, aided by the reappearance of Donna Elvira (Malin Byström), who is determined not to let her seducer go. With Paul Appleby as Don Ottavio, Donna Anna’s eternally steadfast fiancé. Principal Conductor Fabio Luisi leads the Met Orchestra and Chorus.
