Join in on a holiday caroling-styled event that requires no singing. Composer and conductor Phil Kline's interactive, ambient street parade performance "Unsilent Night" comes to Hudson's 20th Anniversary Winter Walk. In this community-friendly event, participants choose one of four specially selected tracks to play on a portable music device: boomboxes, cellphones, ipods, speakers, or a gramophone. (Just kidding.) "We're each playing a separate audio track, which is part of the piece. In effect, we become a city-block-long stereo system," explains Kline. Kline will bring a limited selection of vintage boomboxes, CDs, and cassettes, but participants are encouraged to bring their own devices. WGXC 90.7 FM will broadcast the event live. Download the free Unsilent Night app to participate. December 3. 4pm meetup at Basilica Hudson; the walk departs 5pm from the Warren Street and Front Street intersection.
