If your first inclination is to believe that a story about a man who is too afraid to pursue his beloved because he has a big schnoz is a comedy, you’d be wrong. It’s actually an emotion-filled opera that promises to deliver “delayed passion,” something Americans know nothing about. The performance is the culmination of a farewell season dedicated to Michigan Opera Theatre Founder and Artistic Director David DiChiera, who retires at the end of May. DiChiera wrote the opera based on Edmond Rostand’s play Cyrano de Bergerac and it was first performed by MOT in 2007.
