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".
Hugues Cuénod Hugues-Adhémar Cuénod (] ; 26 June 19026 December 2010) was a Swiss tenor known for his performances in international opera, operetta, both traditional and musical theatre, and on the concert stage, where he was particularly known for his clear, light, romantic and expressive poised interpretation of "mélodie" (French art song). His repertoire encompassed everything from the medieval chansons of Guillaume de Machaut to the avant garde works of Igor Stravinsky, as well as recordings of lute songs. Cuénod contributed to the revival of baroque music, performing compositions by Francesco Cavalli and others. A distinguished singer of Johann Sebastian Bach's music, he was particularly praised for his interpretation of the Evangelist in Bach's "St Matthew Passion". He had the longest career of any recorded vocalist or performer in history: he gave his first concert in Paris in 1928, aged 26, and his last in 1994, when he was 92. He was as fluent in English, German and Italian as he was in his native French.
