In The Guardian, Jonathan Jones wonders why gallery goers aren't blown away. "If Kelly makes you see the sheer beauty of minimalism - as opposed to the ready-made conceptualism it is so often seen as a dumb vessel of - he also connects contemporary, living art with the heritage of Matisse. This makes him one of the most important artists alive, and Tate Modern should maintain this beautiful display of his work as a permanent exhibit. ...Standing in front of Kelly's Broadway, as colour moves towards me in a fiery surge, I feel like a newborn child, seeing the world for the first time. Because abstract can't be explained away, it can't be exhausted. It is always new."
