Nick Cave’s immersive performance art piece HEARD NY premiered at the Grand Central Metro station, filling the space with a gentle rustling sound. Each of the 30 uniquely-crafted horse-suits required two dancers from the Alvin Ailey Dance School to maneuver. The horses “graze” by shifting around and trotting in circles, then breaking into choreographed dance routines set to live music. Presented by Creative Time and MTA Arts for Transit, the performances tale place at 11AM and 2PM every day though the end March.
