WHEN THE WHITNEY moved to its new downtown location, its uptown space was left wide open. Luckily, the Met has stepped in to fill it, creating a new museum dedicated to modern and contemporary art called the Met Breuer. Upcoming exhibits will include a mix of visual art and performances, including photographs by Diane Arbus and a music installation by Vijay Iyer. The space has also been restored to reflect architect Marcel Breuer’s original vision, such as the spaceship-esque lighting in the entrance hall. A must-visit cultural experience this summer.
