Though rarely performed today, the dramma per musica Zelmira is regarded as one of Rossini's most important and musically complex works. Roberto Abbado conducts a cast of noted soloists, including Kate Aldrich, acclaimed as "the discovery of the year" (L'Unita), in the title role of a princess unjustly accused of having killed her father, sung by Alex Esposito. While Gregory Kunde and Marianna Pizzolano stand out for their vocal artistry, the palm goes to star tenor Juan Diego Florez, whose opening aria, with its five high D's and long-held high C, was hailed by Opernwelt as "phenomenal."
