(FILM) Ever wonder what makes Christian rockers rock (other than the love of Jesus)? Well so did the directors of this smart, fascinating documentary, which visits a Christian rock festival in rural Illinois, and allows the swarming hordes of fans and bands to speak for themselves. Many of them sound like fools and slaves, while many others (notably Pedro the Lion's David Bazan), rise to the inquiry with eloquence and artistry. Independently made (and not by a church), this doc screens only once. (911 Media Arts Center, 402 Ninth Ave N, 682-6552. 7 pm, $5–$7.)
