Here is an excerpt from a recent interview I found on YouTube with Arnold Glimcher, the former president of the Pace Gallery in New York, discussing the work of Louise Nevelson:
"What interests me is concepts, is the cognitive process of art. And that process is perception. How is the artist’s perception unique? I don’t think that when you see the most extravagant, extraordinary exhibition of Louise Nevelson’s work, you’re really seeing the art. These are maps or charts or clues to the process that makes the art. The art is Nevelson’s perception of the world. The art is happening in Nevelson’s head. These [the sculptures] are the maps to that art. And I believe it’s true of any artist."
