Ani DiFranco has written hundreds of songs, played thousands of shows, captured the imaginations of legions of followers, and jammed with folkies, orchestras, rappers, rock and roll hall-of-famers, jazz musicians, poets, pop superstars, storytellers and a martial arts legend. She’s “fixed up a few old buildings” and minimized her carbon footprint before it was trendy – from installing a geothermal heating and cooling system in the renovated church that her label calls home to using organic inks on all the t-shirts she sells.
