One can hardly imagine the genre-busting, culture-crossing musical magic of Outkast, Prince, Erykah Badu, Rick James or The Roots without the influence of R&B pioneer Betty Davis. Her style of raw and revelatory punk-funk defies any notions that women can’t be visionaries in the worlds of rock and pop. In recent years, rappers from Ice Cube to Talib Kweli to Ludacris have rhymed over her intensely strong but sensual music.

Her 1974 sophomore album They Say I’m Different features a worthy-of-framing futuristic cover challenging David Bowie’s science fiction funk with real rocking soul-fire, kicked off with the savagely sexual “Shoo-B-Doop and Cop Him” (later sampled by Ice Cube). Her follow up is full of classic cuts like “Don’t Call Her No Tramp” and the hilarious, hard, deep funk of “He Was A Big Freak.”
