Ulay, Marina Abramović’s partner from 1975-1988, sits with her during her performance. This was the first time they “performed” together since The Great Wall Walk (1988), when they each walked over 1,200 miles (2,000 km) along the Great Wall of China starting at opposite ends and meeting in the middle to say their goodbye.
