“Mention the words bel canto (literally ‘beautiful singing’) to most opera lovers and they will think of the works of Rossini, Donizetti and Bellini ….when Callas was asked by Serafin to sing Elvira Puritani, her career achieved some stability as it led to a period of coaching in bel canto roles, and she made house debuts as Norma in London, Chicago, New York Met and in concert in Paris. For her debuts in Berlin and Vienna Callas performed Lucia.” (James Murray)
