Singer-songwriter Ani DiFranco doesn’t like her music to be labeled. Some have called it “folk-punk,” but when asked to define what she does, DiFranco says, “I play music with a story.” Onstage she is mischievous and energetic, interacting with her bassist and drummer, asking the audience questions, bemoaning the latest headlines, and inviting the crowd closer (often to the consternation of security guards). She’s never had anything like a pop hit, but her audiences sing along with every song. DiFranco’s guitar playing is an aggressive combination of flamenco, country blues, and folk strumming. Her lyrics come in torrents and typically combine autobiography, politics, and punchy aphorisms. “My IQ,” for example, from her fourth album, Puddle Dive, includes a recollection of her first menses at thirteen and ends with the line “Every tool is a weapon / If you hold it right.”
