British artist and electronic musician Nick Franglen (of Lemon Jelly) will play a 24-hour piece of improvised music, starting and ending at midnight, in collaboration with the thousands of people who bicycle across Manhattan Bridge during the course of the day. Franglen will be installed in The Archway under the Manhattan Bridge, playing a Theremin with looping effects pedals to create washes of sound. Meanwhile, sensors installed on Manhattan Bridge's pathways, high above The Archway, will register the passing of each bicycle, sending messages to Nick's equipment that imprint a moment of silence on the music for everyone who crosses the bridge. The music will be a unique collaboration between the musician and the bridge users, who will unwittingly guide and develop the character of the piece.
