At that "magical moment between civil and nautical twilight... when your ears are tuned to the wind and your eyes begin to shift from day to night,' Fly by Night begins. 1,800 LED-lit pigeons fly in a coordinated pattern above the East River, taking to the sky from a decommissioned aircraft carrier docked at the Brooklyn Navy Yard. Using whistles and garbage bags tied to the end of bamboo poles, artist Duke Riley and his assistants guide the birds in their illuminated flight for a half hour show on Friday, Saturday and Sunday evenings until June 12, 2016. The free shows, commissioned by the non-profit arts organization, Creative Time, are completely booked, but we are lucky to have this exclusive, behind-the-scenes access to the artist and his process.
