Ferry out of this world to one where 19 international artists bring installation, performance, video, and auditory works to historic Governors Island. For the occasion, Creative Time is opening five buildings not usually accessible to the public, and promises art that questions certainty, beliefs, and the future — all to be contemplated as you bike across the 172-acre island. Some of the marquee names participating: The Bruce High Quality Foundation, Lawrence Weiner, and Patti Smith.
