Basement Films returns for its 13th annual (more or less) celebration of "cinematic un-dependents." A wide range of international, experimental films will be screened over the course of this festival's four-day span. Mind-expanding films and videos from Scotland, Serbia, The Netherlands, New Zealand, Austria, Colombia, Ireland, Portugal and many other nations will be screened at Guild Cinema (3405 Central Ave. NE) and the African American Performing Arts Center (310 San Pedro Dr. NE). This year features a special spotlight on the newly emerging experimental films of Africa. But that's just the tip of the iceberg: Live multimedia performances, interactive projections, lectures, discussion groups and hands-on workshops also abound.
