89. Bonnie Raitt
Her dad was Broadway star John Raitt, but Bonnie's artistic parents were blues giants like Howlin' Wolf and Mississippi Fred McDowell, whom she met and performed with early in her career. She learned fast: Starting with her acoustic slide workout on 1971's "Walking Blues," Raitt rolled out a fearsome repertoire of blues licks, fingerpicking with the best and wielding a slide like an old master. Most of all, she set a crucial precedent: When guitar was still considered a man's game by many, Raitt busted down that barrier through sheer verve and skill.
