I think Ani DiFranco is a great songwriter and performer. "To the Teeth" is a great song and a good album but I would recommend going back to her completely acoustic first album (out of something like 18-20) "Ani DiFranco" recorded I think when she was 18 on her own label. I think it's a masterwork.Highly individualistic and independent, a fine songwriter and a great singer and guitarist IMHO.
