During the 1960s and 1970s, a group of renegade artists left New York City to go to the American Southwest desert to create a series of "desert earthworks." In his documentary Troublemakers: The Story of Land Art, director James Crump chronicles their escapades and shows how they viewed the desert as a blank canvas. The movie makes its Cleveland debut tonight at 7 at the Cleveland Museum of Art. It screens again at 7 on Friday night. Tickets are $9. (Niesel)
