Ani DiFranco doesn't really expand her sonic palette on Dilate, but she doesn't need to.
DiFranco racked up a dedicated cult audience on the basis of her conviction.
There's not much melody on any of her songs, but there are messages and, thankfully, a fair share of humor.
Dilate suffers from a bit too much repetition, but when DiFranco lands on a good hook -- such as "Superhero" or "Done Wrong" -- the results suggest that she could reach a wider audience.
