This summer, the Hauser & Wirth Gallery on Savile Row is getting quite dirty, both literally and figuratively. But who is to blame? The answer is: Californian artist Richard Jackson, who transformed the neat and white exhibition space in a messy and colorful shambles. A few steps away from the building, you can already see that “something happened”. Without even entering the space, you distinguish a massive yellow horse put upside down on a bright pink base, some rainbow paint splashes on the walls, and in the center, a funny smiling clown doing acrobatics.
