Documentarian Michael Lahey recounts the brief but rocky history of the Tucson pirate station KAVL FM, which was launched in response to the 1996 Telecommunications Act that permitted media monopolies to buy up more local stations. It’s a chilling and instructive tale about the curtailment of free expression, though Lahey’s video (2004, 64 min.) favors crankiness and jokey found footage over polemics. A better reason for attending this program is Paul Chan’s Untitled Video on Lynne Stewart and Her Conviction, the Law, and Poetry (18 min.), an experimental yet plainspoken work in which the radical human-rights lawyer, unjustly convicted in February 2005 of aiding foreign terrorists, reads poems and reflects on her life and prospects while Chan finds original and lyrical ways of depicting her.
