[Unsilent Night last year by Bobby Williams]
Time for the annual Unsilent Night, the boombox caroling walk... Composer Phil Kline's holiday tradition got its start in 1992... meeting place is 7 at the Arch at Washington Square Park... and the group makes its way over to Tompkins Square Park.
The official website is here. The Times has a piece on the new Unsilent Night app here. Still, long live the boombox.
