The Boswell Sisters
The Boswell Sisters were an American close harmony singing trio. They were three sisters: Martha Boswell (June 9, 1905 – July 2, 1958), Connie Boswell (later spelled "Connee", December 3, 1907 – October 11, 1976), and Helvetia "Vet" Boswell (May 20, 1911 – November 12, 1988). They came from uptown New Orleans. The group blended intricate harmonies and song arrangements featuring effects such as scat, instrumental imitation, ‘Boswellese’ gibberish, tempo and meter changes, major/minor juxtaposition, key changes, and incorporation of sections from other songs. They were famous in the United States in the 1930s at the end of the Jazz Age and the start of the Great Depression.
