This photo from the Abramović opening is kind of touching. Her performance in the MoMA atrium is not supposed to include any interaction with those who sit across from her.
The caption from the Facebook album reads:
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.
Somebody in the comments asks the obvious: “I thought there was to be no interaction with the art.” To which the moderator responds: “Correct, no interaction, but this was her partner in life and art for 12 years who she has had almost no contact with since 1988…”
