Ryan Trecartin: This guy is a force of nature. Hyper technology, mass hysteria, family drama. Please run for public office! Video: Part 1 of 5, Family Finds Entertainment
Gunter Brus: He and Otto Muhl pioneered Viennese Actionism ('body art' before it was painted Sports Illustrated models or mud-smeared hippies). My husband and I had the odd pleasure of meeting Mr. Brus in Bruges a couple of years ago. The photographic documentations of his performances are particularly strong; he used black paint which, when seen in black and white film, may or may not be blood. Image: Self Painting #2, 1964
Charlie White: Combining CGI monsters, greased-up adolescents, muppets, and transvestites can never, ever be wrong. It's difficult to choose just one image. His website is here and videos here. Image: Getting Lindsay Linton, 2001
Paul McCarthy: Still, Piccadilly Circus, 2003. Painter is a classic and my all-time favorite video.
