Watch Montserrat Caballé in a 1971 conversation with Bernard Levin as they discuss the first moment she knew she would be an opera singer; early rejections auditioning in Italy; debuting at Glyndebourne by learning the Marschallin in Der Rosenkavalier over the course of 20 days; stepping in for Marilyn Horne to make her New York debut singing in Lucrezia Borgia; why she sang the bel canto repertoire; and the demands of scheduling performances four years in advance. Bonus studio performances of arias from Tannhäuser, Le Nozze di Figaro, Lucrezia Borgia, Norma, and Il Trovatore, are sprinkled throughout the interview. Watch the entire 72-minute clip after the jump.
