It was the late '70s when artists Marina Abramović and Ulay began performing out of vans and fell in love. The relationship sadly came to an end, and they decided to walk the Wall of China to share one last embrace. That was the last time they saw one another. By 2010, Marina had a new art project. She would sit in silence with complete strangers. On the opening night, guess who showed up? None other than Ulay! Watch what happens!
