The titular troublemakers are the New York–based Land (aka Earth) artists of the 1960s and 70s, who walked away from the reproducible and the commodifiable, migrated to the American Southwest, worked with earth and light and seemingly limitless space, and rethought the question of scale and the relationships between artist, landscape, and viewer. Director James Crump has meticulously constructed Troublemakers from interviews (with Germano Celant, Virginia Dwan, and others), photos and footage of Walter De Maria, Michael Heizer, Robert Smithson, Nancy Holt, and Charles Ross among others at work on their astonishing creations.
