Ani DiFranco

With 18 albums in as many years under her belt, the Folksinger wasn't kidding when she called her latest release Canon. A stellar introduction for Ani neophytes, the album contains 30 previously released tunes culled from nearly every album in that impressive catalogue, including her 1989 self-titled debut and 2006's Reprieve. Diehard fans will also find a few buried treasures: five new renditions of classic songs, including "Napoleon," "Shameless," "Your Next Bold Move," "Overlap" and "Both Hands" (a tune the writer Sara Marcus once called the lesbian national anthem).
