Queens of Jazz is a celebration of some of the greatest female jazz singers of the 20th century. It takes an unflinching and revealing look at what it actually took to be a jazz diva during a turbulent time in America's social history - a time when battle lines were being constantly drawn around issues of race, gender and popular culture. This is a documentary about how these women triumphed - always at some personal cost - to become some of the greatest artists of the 20th century; women who chose singing above life itself because singing was their life.
