The Metropolitan Opera: Il Trovatore: Verdi’s IL TROVATORE again storms the Met stage in a star-studded, anvil-wielding cast , including Sondra Radvanovsky, Dolora Zajick and Dmitri Hvorostovsky. Marcelo Álvarez sings Manrico, the troubadour of the title. The story is well-known already: The gypsy Azucena has harbored a grudge for thirty years, but she is about to have revenge at last. Meanwhile, her son Manrico is in love with Leonora, but so is his arch-enemy, the Count Di Luna. A pot-boiler, where every tune is a hit.
