Time Out says
Join a roving group of revelers as they parade through the NYC streets with boomboxes blaring music. Composer Phil Kline will lead the procession from the Washington Square Arch to Tompkins Square Park. Kline will offer up vintage boomboxes for his collection along with cassettes and CDs for those who bring their own. Or just download the MP3 tracks and you’ll be ready to march and party. Arrive by 5:45pm. All ages.
