WILLIAMSBURG If you haven’t quite gotten into the swing of 2011, the festivities at the Music Hall of Williamsburg will let you revisit the holidays one more night. A gift swap and photobooth are among the party favors at this variety show, featuring the five-piece, highly melodic pop outfit Xylos, new-new-wave band Living Days, short films from members of the FilmShop, DJ Jan Woo and VJ Shantell Martin. Doors 8, $10.
