Hedonia on visionary SF artist Richard Powers:
What would a Martian's dreams be like? Well, if there were (are, will be) Martians and assuming that they could dream, their dreams would most likely be like Richard Powers' paintings and illustrations for science fiction publications. Powers' illustrations introduced the subconscious fantasies and dream-states of the surrealist art movement to its ultimate partner, science fiction. In doing so, he revolutionized the entire field of science fiction illustration, spurring record sales for his first steady client, Ballantine Press, and spawning countless imitators.
Powers is one of my all-time favorites; I consider him at least the equal of Dali and Ernst.
