In what should be a highlight of the new season, soprano Anna Netrebko sings her first Met Aida, going toe-to-toe with mezzo-soprano Anita Rachvelishvili as Amneris. With the epic backdrop of ancient Egypt, Aida is packed with magnificent choruses, complex ensembles, and elaborate ballets.  Few operas have matched Aida in its exploration of the conflict of private emotion and public duty, and perhaps no other has remained to the present day so unanimously appreciated by audiences and critics alike.
