Erwin Wurm: “His sculptural work is great too. A house coming off the side of a museum, fat cars — it’s brilliant. With Cattelan’s work you have this darker, sharper look that appeals more to your head than your eyeballs, but Wurm’s is much more approachable. A lot of it is visually funny. I also like how he jumps mediums as well, from sculpture to photography.” Above: Wurm’s “Truck” (2005)
