There are unknown artists and there are legendary masters. Rarely could one man be described as both. Abstract expressionist Clyfford Still, however, was one and the same. After a retreat from the art world in the 1940’s, he controlled who got to see his canvases – and how. But his influence on Pollack, Newman, and Rothko was profound. An eponymous museum in Denver maintains some 2,500 of his works – everything in Still’s possession at the time of his death. Seen collectively they give rise to the idea that Still was not merely a painter of individual artworks but the architect of a grand symphonic vision.
