Her hair may have inspired Rogue from The X-Men, but Bonnie Raitt's a true inspiration to those of us living outside the Marvel universe as well. Being a female guitarist in a world dominated by men with names like Slash and Howling Wolf is a hard road, but Bonnie's dedication to her craft has gotten her all the way to the Rock and Roll Hall of Fame.

She's not only a pioneer, she's also overcome her fair share of struggles: dropping out of Harvard to follow her musical mentor, struggling with drug and alcohol abuse, getting dumped by her record label only to come back with two best-selling albums, and standing by her principles when she came under fire for making negative comments about then-president George W. Bush. Through it all, though, she's remained a voice of compassion and an amazing talent.

She's less known, but equally commendable, for her political activism, including civil rights agitation, anti-apartheid work, and early interest on global warming and clean energy. Plus, who doesn't love a woman who not only embraced her first gray streaks, but makes salt and pepper hair look dead sexy? Bonnie really has given them something to talk about, and we love her for it.
