Ani DiFranco at the Tarrytown Music Hall

Ani DiFranco drew fans from near and far to the Tarrytown Music Hall on Thursday night. DiFranco sang from her vast songbook, played songs from her new album, "Red Letter Year." She also previewed, "Which Side Are You On?"— the song she is slated to perform at Pete Seeger's 90th birthday celebration. Metromix was there, flashing away.
