A Marina Abramović moment—in collaboration with her former creative and romantic partner Ulay—to kickstart Monday. The aim of this piece, titled Relation in Time, was to “explore the concept of deriving energy from [an] audience,” in the words of Glenn Lowry for MoMA. The pair sat back to back, alone in a gallery space, bound to one another by their hair, for the purpose. They remained there for 16 hours, only allowing the audience to enter the room once they’d reached the point of utter exhaustion. “We wanted to know how we [could]… use the energy of the public to push our limits even farther, and to sit one hour longer,” the famously patient Abramović explained.
