Gladys Alberta Bentley (August 12, 1907 – January 18, 1960) was an American blues singer, pianist, and entertainer during the Harlem Renaissance. Her career skyrocketed when she appeared at Harry Hansberry's Clam House in New York in the 1920s, as a black, lesbian, cross-dressing performer. She headlined in the early 1930s at Harlem's Ubangi Club, where she was backed up by a chorus line of drag queens. She dressed in men's clothes (including a signature tail coat and top hat), played piano, and sang her own raunchy lyrics to popular tunes of the day in a deep, growling voice while flirting with women in the audience.
