We take an in-depth tour of the huge new William Blake exhibition at Tate Britain and explore the life and art of this brilliant yet complex visionary. And in New York, we talk to Marc Glimcher about Pace's eight-floor gallery in Chelsea and what this and the glut of other expanding galleries tell us about the market in New York.
