Montserrat Caballé

María de Montserrat Viviana Concepción Caballé i Folch was a Spanish operatic soprano. She sang a wide variety of roles, but is best known as an exponent of the works of Verdi and of the bel canto repertoire, notably the works of Rossini, Bellini, and Donizetti. She was noticed internationally when she stepped in for a performance of Donizetti's Lucrezia Borgia at Carnegie Hall in 1965, and then appeared at leading opera houses. Her voice was described as pure but powerful, with superb control of vocal shadings and exquisite pianissimo.
