This season’s L’Elisir d’Amore at the Metropolitan Opera did not get much publicity. But opera fans know it should be good. That’s why the house was pretty packed the night I attended. I (and, judging from the applause, most of the audience) was not disappointed. Juan Diego Florez and Diana Damrau were both making house debut in these roles. Florez as the cute but intellectually challenged Nemorino, and Damrau as the sassy but golden-hearted Adina. All I can say is: What took them so long to sing these roles at the Met! They were funny, charming, athletic. And they both can sing notes so high that glasses shatter!
