Betty Mabry Davis, a talented songwriter from a small steel town, challenged conventions for women with her bold personality, distinctive style, and innovative funk music. She became friends with Jimi Hendrix and Sly Stone, wrote songs for artists like the Chambers Brothers and The Commodores, and married Miles Davis, influencing his transition from jazz to funk. In the 1970s, she captivated audiences with her energetic blend of hard rock and blues-infused funk, inspiring musicians from Prince to Erykah Badu to Karen O and Peaches. Then, she disappeared.
