Arguably the greatest jazz vocal group of all times, New Orleans' Boswell Sisters, Martha, Vet and Connee were also talented musicians: Martha played piano, Vet played violin, banjo and guitar, and Connee played cello, saxophone and guitar. After playing in local vaudeville, their careers took off when a local radio station gave them a daily singing program. The sisters' close and complicated harmonic vocals, scatting and numerous tempo and key changes was unique in their era and has never been equalled.
