The art of Anselm Kiefer: "Becoming the Sea"‎

Anselm Kiefer, one of the world's most prolific living artists, is now the subject of a retrospective in St. Louis. He talks with Mark Whitaker about how rivers cutting through America's Midwest, and a Beat Generation poet, inspired his three-story-tall abstract canvases, in a show entitled "Becoming the Sea."
