It's appropriate that the 7:30 p.m. screening of Cowtown Ballroom ... Sweet Jesus! at the Lawrence Arts Center (940 New Hampshire, 785-843-2787) is a benefit for KAWR, a Lawrence community-radio station looking to get off the ground. Much like the guys behind Good Karma Productions — the management team that ran the midtown concert venue in the 1970s — KAWR's organizers are looking to enlighten the community. And just as the Cowtown Ballroom was an incubator for regional acts such as Brewer and Shipley and the Ozark Mountain Daredevils, the burgeoning radio station has set out to help nascent talent develop and hone skills while providing an invaluable venue for local issues and information. See the documentary, followed by a Q&A with producer-director Joe Heyen and writer, editor and director of photography Anthony Ladesich. Tickets cost $10.
