Today’s Christmas Song of the Day needs no explanation. GWAR, the infamous costumed heavy metal band, are making their yearly appearance at the 9:30 Club tonight. A couple years back they went out caroling and taped it, so prepare yourself for one of the most epic videos you will see all year.

GWAR play tonight with Kepone and Iron Reagan at the 9:30 Club. Tickets are $25 and be sure to wear all white.
