Breakthrough Moment?

From the Metropolitan Opera comes the news that soprano Erin Morley will sing all performances of Sophie in the upcoming Rosenkavalier, replace Mojca Erdmann, who is recovering from pneumonia. Best wishes to Erdmann for a complete recovery, but based on my experience of them both - Erdmann as an out-of-tune Forest Bird in the Met HD broadcast of Siegfried, Morley as a glorious Roxana in Santa Fe's King Roger last year - the Met audience is better off with this cast change.

Morley has sung almost 60 Met performances, but they've been in small roles. Hoping this will be a big breakthrough for her.
