Ray Hill has crafted a cottage industry out of rabble-rousing, be it for gay rights, prison reform or the preservation of topless bars and smut stands. Ray Hill, the Prison Years, a revival of the one-man show by the burglar-turned-activist, includes Hill's thoughts about "prison life, the 'system' and [his] run-ins with Houston's finest." The final performance starts at 8 tonight. The Little Room Downstairs, 2326 Bissonnet, 523-0791. $10.
