Abstract
Despite their lack of recognition today, the Boswell Sisters of New Orleans were America’s greatest jazz vocal group. They changed popular music from the 1930s forward. This essay explores their roots in New Orleans, defines the unusual aspects of their sound and recordings, and identifies their influences on other vocal groups, singers, and the Big Bands. Also examined is the status of Boswell recordings and performances over the decades, including an apparent resurgence in recent years.
