After 20 years in the music biz, self-described “Little Folksinger” Ani DiFranco is still technically little, although her influence on fellow musicians, activists, and indie-minded people the world over has been huge. She still proudly identifies as a folksinger, too, but her understanding of that term has always been far more expansive than a bin at the record store or a category on iTunes, with ample room for soul, funk, jazz, electronic music, spoken word, and a marching band or two. Over the course of more than 20 albums, including the live double CD Living in Clip (1997) and the two-disc career retrospective Canon (2007), as well as the latest one, ¿Which Side are You On? (2012), Ani has never stopped evolving, experimenting, testing the limits of what can be said and sung. Her lifelong tribe of co-conspirators includes everyone from Pete Seeger and the late Utah Phillips to a new generation of twentysomething singer-songwriters who grew up with her songs and shows — and then there's the motley crew of folks like Prince, Maceo Parker, Andrew Bird, Dr. John, Arto Lindsay, Bruce Springsteen, Chuck D, the Buffalo Philharmonic, Gillian Welch, Cyndi Lauper, and even Burmese activist and Nobel laureate Aung San Suu Kyi, with whom she has crossed paths in a myriad of ways.
