Watermill Center, NY. Not that far from Marina Abramovich's house. She likes it there. So do most celebs you can think of. Lady Gaga, Sarah Jessica Parker, the Greatest Showman too… the list goes on. Though many of the most "interesting" photos look like they've been removed (bing) from last I dug many months ago.
Tons of performance art for your visual pleasure. And of course lots of events for the rubbing of elbows with other occult-loving peeps.
Fun times at the Watermill Center.
