This week's art scene is a little slower-paced than usual. But it's only the calm before the storm -- next Tuesday, Santigold is headlining MoMA's Party in the Garden, with a special After Party DJ set by Solange Knowles. Until then, there are a number of End of Year student exhibitions, including Cooper Union and Hunter College. Also: the Met reopens its Roof Garden, and Tom Sachs has transformed the Park Avenue Armory into a Martian landscape. So put on your Moon Boots, y'all, and check out this week's art scene. More»
