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".
Eunice Alberts Eunice Alberts (1927–2012) was an American contralto who had an active career as a concert soloist and opera singer during the 1950s through the 1980s. She began her career as a concert soloist with the Boston Symphony Orchestra at the young age of 19 and quickly became a lauded oratorio singer during the late 1940s and the early 1950s. She began her opera career with the New York City Opera in 1951. She went on to have a successful opera career with companies throughout the United States, ultimately forging a strong partnership with Sarah Caldwell's Opera Company of Boston that lasted from 1961 to 1988. She notably sang in a number of United States premieres in Boston and appeared in a few world premieres in New York City. Although Alberts made a number of impressive achievements in the field of opera, her legacy remains in the numerous appearances and recordings she made with major symphony orchestras in the United States. She was particularly successful as a soloist in the great choral works of J.S. Bach, Joseph Haydn, Wolfgang Amadeus Mozart, and Ludwig van Beethoven.
