For the fourth year in a row, New Music Collective hosts Boombox Christmas Caroling with Phil Kline's Unsilent Night. Create a roving sound installation, where boomboxes replace voices in a holiday caroling event like no other. You bring a boombox, iPod (Zune!?) with speakers, or any media playing device you wish, and organizers supply a CD, tape, or digital download of one of the four parts of the piece. RSVP required: firstname.lastname@example.org.
