Adele Addison (born July 24, 1925 in New York City) is an American lyric soprano who was a figure in the classical music world during the 1950s and 1960s. Although she did appear in several operas, Addison spent most of her career performing in recital and concert. Her performances spanned a wide array of literature from the Baroque period to contemporary compositions. She is best remembered today as the singing voice for Bess (played by Dorothy Dandridge) in the 1959 movie, Porgy and Bess. Known for her polished and fluent tone, Addison made a desirable Baroque vocal artist. She can be heard on numerous recordings, of which her Baroque performances are perhaps her best work. Many of her recordings were made with the New York Philharmonic under the baton of Leonard Bernstein.
