Robert Motherwell was a leader and perhaps the master of Abstract Expressionist Art
from the late 1940s thru the 70s. He worked in drawing, painting and collage often
mixing the techniques. He was also the main intellectual spokesman for the Abstract
Movement producing a number of papers and books. Watching him work and also talk about it is a real joy for anyone wanting to know about how a master goes about his art-making.
Another fine film about the same era but with many more artists is "Painters Painting" which is now available on DVD.
