Marina Abramovic and Ulay, Relation in Time (1977)
Duration: 17 hours
This piece started without the public. Marina and Ulay tied their hair together, sitting back to back for 16 hours in the gallery, with only the gallery staff present. Each hour, three minutes of video was taken and they were photographed. After 16 hours, when their bodies were close to total exhaustion, the public was invited to enter. Marina and Ulay wanted to know how they could use the energy of the public to push their limits even further. They performed for the public for one more hour, for a total performance time of 17 hours.
