For American Opera Projects’ reading this weekend of his first opera, the theatre composer Stephen Schwartz has mustered a mighty trio of sopranos. Alongside the imperial Lauren Flanigan in the leading rôle of Myra, Séance on a Wet Afternoon features L. A.’s Hila Plittman, the Dawn Upshaw of her generation: and Caroline Worra, going from strength to strength. Time Out New York features my salute to Caroline here.
