"Visconti’s sensational 1955 production of LA SONNAMBULA for La Scala, Milan, was revived and recorded two years later. As a girl, Callas had fallen in love with the rôle of Amina; as an adult it suited her voice perfectly, and her interpretation set a benchmark that few have equalled. Among the many highlights of Callas’s profoundly satisfying performance is her cadenza for Ah non giunge in which she executes a remarkable diminuendo on a stratospheric E-flat, a feat unrivalled in the history of the gramophone. This is by any standards a classic recording."

“While best known for the fiery, scenery-chewing Verdi roles such as Azucena, Amneris, Lady Macbeth, and Eboli, Fiorenza Cossotto was also a prominent performer of bel canto parts such as Rosina in Rossini's BARBIERE, Leonora in LA FAVORITA, and Adalgisa in NORMA. Such large and powerful mezzo voices, particularly with a secure top, are rare compared to the lyric mezzo, and from the late 1960s through the early 1980s, she was THE Verdi mezzo, the successor to Simionato and the predecessor to Zajick.”
