Lumpen and Public Media Institute produce this annual festival, now in its fifth year, focusing on radical art, media, technology, and politics, with an emphasis on work generated by underground and activist communities. This year’s festival continues through Sunday, May 7, in Bridgeport and scattered other locations and includes neighborhood tours, workshops, numerous public art installations and interventions, barbecues, film/video screenings, music, and performances. All events are at the Version Kunsthalle–aka Iron Studios, 3636 S. Iron, first and fourth floors–unless otherwise noted. Participating venues include South Union Arts (1352 S. Union), Skylark (2149 S. Halsted), and McCormick Tribune Student Center (33rd and State). Events are free, unless otherwise noted. An Event Pass allows admission to all screenings and events ($25); a Version Pass includes all that plus meals, the Select 10 DVD, Lumptronic 7 CD, Version posters, Select 9 Agit Prop Poster magazine, and assorted stickers and festival ephemera ($50). Below is a schedule of selected festival events. For updates and additional information, visit www.versionfest.org or call 773-837-0145.
