Not sure what you mean by this? You're comparing him favorably to the modernists? Picasso, Braque, Miro, those guys? Or do you mean specifically abstract expressionists, who seem to get so much flak in this community? Pollock and Rothko are actually pretty miraculous if you see their paintings in person. So yeah... This didn't make much sense.
Have you seen any of Prince's work in person?
Nope, and I'm not criticizing his work based on this article (I defend him elsewhere in this thread). But the GP's comment was over road to the point of being nonsensical. I just wanted to point that out.
