Our World included the opera singer best known for what technique?
Maria Callas Maria Callas, Commendatore OMRI (Greek: Μαρία Κάλλας ; December 2, 1923 – September 16, 1977), was a Greek-American soprano, and one of the most renowned and influential opera singers of the 20th century. Many critics praised her "bel canto" technique, wide-ranging voice and dramatic interpretations. Her repertoire ranged from classical "opera seria" to the "bel canto" operas of Donizetti, Bellini and Rossini and further, to the works of Verdi and Puccini; and, in her early career, to the music dramas of Wagner. Her musical and dramatic talents led to her being hailed as "La Divina".
Cesira Ferrani Cesira Ferrani (May 8, 1863 in Turin – May 4, 1943 in Pollone) was an Italian operatic soprano who is best known for debuting two of the most iconic roles in opera history, Mimì in the original 1896 production of Giacomo Puccini's "La bohème" and the title role in Puccini's "Manon Lescaut" in its 1893 world premiere. Ferrani sang a wide repertoire that encompassed not only verismo opera but the works of composers like Verdi, Gounod, Wagner, and Debussy.
