Lucia di Lammermoor
From the San Francisco Opera website:
Pressured to marry the wrong man, a young woman suffers an emotional breakdown, culminating in the most astonishing mad scene in all of opera.
Witness the arresting vocal and dramatic power of Nadine Sierra and Piotr Beczala in a striking new production by Director Michael Cavanagh and Set Designer Erhard Rom (Susannah, 2014). Music Director Nicola Luisotti conducts the gorgeous, melodic score.
