New York City artist Phil Kline conceived of Unsilent Night in 1992, when he elevated the concept of holiday caroling into performance art spectacle. Since then, his event has taken off, spawning happenings in over 50 cities, including Athens. Kline's multi-track, 45-minute experimental electronic piece shimmers with wintry mystery and is designed to be played simultaneously on as many devices as possible: Attendees can bring a boombox to the event, where organizers will have tapes and CDs handy, or visit unsilentnight.com beforehand to download one of the four tracks to their smartphone or mp3 player. For the Athens event, organized by Mark Mobley, participants are invited to gather at Little Kings Shuffle Club at 7:30 p.m. Saturday, where they will collectively hit "play" and stroll through the festively lit streets of downtown Athens.
