The Boswell Sisters were an influential American vocal jazz trio from New Orleans, consisting of sisters Martha, Connie (later spelled "Connee"), and Helvetia "Vet" Boswell. Born between 1905 and 1911, the sisters were raised in a musically inclined family and trained in classical music, but were ultimately drawn to the vibrant jazz scene of New Orleans. They formed their singing group in 1925, quickly gaining attention for their intricate harmonies and rhythmic experimentation.

The Boswell Sisters achieved national prominence in the early 1930s, collaborating with notable musicians such as the Dorsey Brothers, Glenn Miller, and Benny Goodman. Their innovative style, which included scat singing, instrumental imitations, and surprising tempo changes, had a significant impact on the development of the big band sound and influenced future vocal artists like Ella Fitzgerald and the Andrews Sisters.

Despite their success, the group disbanded in 1936 when Martha and Vet chose to retire and focus on their families. Connie continued as a solo artist, enjoying a successful career in radio, film, and television. The Boswell Sisters' legacy endures, as they are celebrated for making jazz more accessible and appreciated by a wider audience. Their groundbreaking work continues to inspire musicians and music enthusiasts alike.
