Mr. Brainwash, a provocative figure in the world of street art, practices an irreverent brand of appropriation characterized by the use of copyrighted images from history, popular culture, and art history. The artist subtly alters the picture or its context, mischievously undermining the tone of the source material. Brainwash, a pseudonym for Thierry Guetta, is known for producing massive spectacles to display his art. He came to prominence through mounting large-scale public projects in his current home of Los Angeles and as the main figure in the Banksy-directed film Exit Through the Gift Shop. His work hinges on the idea that anything is possible in his practice. “Art has no walls. Anybody can be an artist,” he says. “Art has no rules. There’s no manual.”
