The weather’s getting chilly, the lights are up in Hampden, and the Salvation Army bells are a-ringing outside the market. Yes, the holidays are just around the corner here in Baltimore and that means that it’s time once again for our annual performance of Phil Kline’s ambient Christmas classic, Unsilent Night, Baltimore’s best boombox Christmas parade. For the third year running, Baltimoreans will take to the streets and spread noisy Xmas cheer to everyone within earshot. This year’s festivities will kick off at 8 p.m. at the Male/Female sculpture in front of Penn Station, where tapes and CDs will be distributed. It is recommended that you arrive no later than 7:45 p.m. to claim your copy of the piece. We’ll then wind our way around the streets, head over to the Meyerhoff, inside the Charles Theater and finally end up at the door of the Metro Gallery, where the Unsilent After Party, featuring music by Parachute Musical, Pianowire, and The Noises 10, will be awaiting us. (N.B. There is a $7 cover charge.) Visit www.unsilentbaltimore.com for all the dirty details.
