Widely acclaimed during his lifetime, American painter Charles Ephraim Burchfield (1893 - 1967) is curiously under-appreciated today. But an ambitous new touring retrospective, curated by artist Robert Gober, may change that. HEAT WAVES IN A SWAMP, which opens in June at New York's Whitney Museum, features over one hundred works by the visionary artist. Working predominantly in watercolor, Burchfield painted the landscapes around his upstate New York home, depicting nature as a transcendental, mystical force. In their hallucinatory qualities, some of his later period landscape paintings, like the images above, almost prefigured psychedelic art. Here's to hoping the exhibition gives Burchfield the recognition for his influence he so deserves.
