Bradley Beesley’s bona fides include countless collaborations with the Flaming Lips, so his fascination with a rodeo whose performers are state and federal prisoners is understandable. Oklahoma’s rodeo-as-rehabilitation program began back in 1940 and, if the shots of its vintage poster art are any indication, its popularity stemmed from its retribution justice masked as neo-Roman entertainment, though its current incarnation is not quite as sadistic. Among the colorful and somber portraits, none is as memorable as Danny Liles, a wild-eyed enthusiast who despite a 20-plus-year sentencing for homicide has a childlike exuberance that could win over the most hardened parole-hater. Like its subject, Sweethearts of the Prison Rodeo is a curious blend of healing and barbarism.
