In the early 1930s, Connee, Vet, and Martha Boswell, three sisters from New Orleans, were among the first to introduce jazz sensibilities into a pop vocal format. Their signature sound was a sophisticated brand of close, jazzy harmony coupled with bluesy inflections and jazz-influenced phrasing. The Boswell Sisters worked with some of the premier bands of the era, including those of the Dorsey Brothers and Glenn Miller. Though the trio was enormously influential on countless jazz and pop singers, they disbanded by the mid-'30s, with only Connee pursuing a solo career.
