Watch VoirFilms. The story of Cio-Cio-San, called Butterfly, a young Nagasaki geisha who, abandoned by her American lover after giving birth to their son, ultimately kills herself, continues to impress audiences today. In this outstandingly authentic and elegant production from the Sferisterio Opera Festival, Puccini's highly emotional music is expertly delivered. The superior cast is headed by Raffaella Angeletti, "certainly one of the best Butterflies of our time" (ForumOpera.com), who has performed this role in many Italian theatres, as well as in Madrid and at the Vienna Staatsoper.
