Frank Stella is “probably the world’s most famous living abstract artist. He is 70 years old and on the short side, but he has a sweeping, imperious manner. He was born in Massachusetts and studied at Princeton University. His frequent pronouncements about art are flavoured by a generous dollop of intellectual pride, which goes strangely with his high-pitched New York voice – comedic shades of Woody Allen or Joe Pesci. ‘I only really care about the immediate impact that art has on you,” he says. “I like all the other things that go after, but I can’t help it, I go by the first hit’.”
