Leonora, the main female character of Il trovatore, embodies like no other Verdian heroine absolute devotion and faithfulness, until her ultimate sacrifice to save her lover. One of the most tragic roles of the bel canto repertoire, it is very vocally demanding, requiring a wide ambitus and virtuosity. Having triumphed in Leonora on all world stages, Maria Callas bade farewell to the role in this stunning recorded version, conducted by Karajan and surrounded by a five-star vocal cast.
