Willie Mae “Big Mama” Thornton exuded uncompromising intensity. Her voice conveyed struggle and defiance, fury and hurt, like few others. Standing at 6ft 2in, with an imposing physique and a razor-scarred face, she was a Black, gay multi-instrumentalist who refused to let a racist society or a rapacious industry confine her.
Thornton should be ranked alongside the likes of Billie Holiday and Nina Simone, but instead she is little more than a footnote in the histories of Elvis Presley and Janis Joplin as the original voice behind songs they would make famous. A new documentary, Big Mama Thornton: I Can’t Be Anyone But Me, aims to right this wrong.
