Ani DiFranco's fondness for cheeky self-effacement marks her fourth album, Not a Pretty Girl. Having redefined our whole concept of cult following, the funky, punky singer/songwriter has parlayed her prowess for six-string blues guitar into an unique alternative acoustic sound. This album marks real growth for the musician. Songs like the title track or "Worthy" are more fully realized than many of her earlier pieces that lean toward artful scat or spare guitar and vocal arrangements. It also precedes DiFranco's more experimental work, a characteristic recurrent with increasing frequency on subsequent recordings. --Nick Heil
