Well, SantaCon has come and gone, but you still have that urge to make with the merry this holiday season, preferably through participatory art? Well, you're in luck -- San Francisco is hosting its annual performance of Phil Kline's Unsilent Night tonight.

Unsilent Night is music intended to be played on cassettes in boomboxes on a stroll through the city, so participants become in essence a big stereo system, playing Christmas carols (yeah, sort of like KOIT, if they played the Kronos Quartet). The original Unsilent Night was performed in 1992 on a walk through a block in the East Village, and now the piece is performed every year in New York, San Diego, Vancouver, and Cleveland, along with SF, and a number of other cities throughout the world.

If you're interested in participating, bring a boombox with a cassette player and fresh batteries and meet up at Dolores Park before 7 p.m. (RSVP so they'll know how many tapes to bring; if you don't have a boombox, you can borrow one). The group will be walking around the Mission, Noe Valley, and the Castro for about 45 minutes so bundle up too.
