Montserrat Caballe, one of the greats of 20th-century opera, is being remembered on what would have been her 89th birthday. Nicknamed “La Superba”, the Catalan singer began her career in Switzerland, Germany and Austria before becoming a superstar on the world stage. She made her American debut in Donizetti’s Lucrezia Borgia at Carnegie Hall in New York City on 20 April 1965, replacing the pregnant Marilyn Horne and earning a 25-minute standing ovation.
