Marina Abramović and Ulay’s relationship is the artwork that keeps on giving. In 1988, they ended their 12-year relationship as lovers by crossing the Great Wall of China from each end, and in 2010, they taught the world about the pure power of human reunification when Ulay appeared at Abramovic’s 2010 performance The Artist is Present at MoMA. Now, Richard Saltoun gallery in London reveals it will show a rarely seen film made by Ulay with Abramovic in an exhibition of special Ulay works.

The news comes as Ulay signs with the gallery. “We’ll show some of Ulay’s 1970s polaroids,” Saltoun tells the Art Newspaper, “and a relatively unknown 1970s film showing Marina and Ulay driving their van round and round the square between the Palais de Tokyo and Musée d’Art Moderne in Paris (Relation in Movement, 1977),” Saltoun says. “You can’t see their faces, it’s a performance.”

While Ulay is most famed for being Abramović’s ex-lover, he has artistic merit in his own right. His early polaroid works, that will go on show at Saltoun, are examples of his self-created ‘Auto-Polaroid’ movement where he used the medium of Polaroid photography and his body as a canvas to explore the human condition.
