Cuban performance artist Alejandro Figueredo Diaz-Perera plans to spend three weeks living inside the walls of a Chicago art gallery. He’s titling this performance piece “In the Absence of a Body.” While living inside the 2.5-foot-wide corridor, Diaz-Perera will do only the most essential actions of his quotidian life: sleep, eat, and personal hygiene. He will not communicate with anyone on the other side of the walls. While he will be able to observe the audience, Diaz-Perera will remain invisible to them. Until the close of the exhibition, Diaz-Perera will attempt to embrace the act of becoming a Ghost of himself, an absence, nothing.
