Through an intimate study of the body’s mental and physical limitations, Miles Greenberg’s Oysterknife was an emotional and ephemeral performance that live-streamed him walking on a conveyor belt for an uninterrupted 24 hours. Jeffrey Deitch celebrates the artist’s severe exploration of ritual with a 24-hour screening of the account.

With this heroic act, Greenberg says,“Oysterknife is my love letter to the performance art of the 1970s, and more specifically to the great Black pioneers of endurance such as Senga Nengudi, Pope.L, and David Hammons. Endurance work, at a certain point, necessarily involves a degree of spectacle around bodily deterioration. I feel my body being consumed every day. I’m within my comfort zone so long as I have agency over the poetics of that consumption. But here, I wanted to let go of that, just to see what would happen. This is real physical pain—it always is—but this time, that pain isn’t wrapped up in metaphor.”
