The Berlin Wall and the soldiers that guarded it kept residents of East and West Germany separate for decades, but that fortress of concrete and metal couldn’t keep Western culture out of the East. And at the peak of intra-Germanic tension in the 1980s, East Germany was really, really into hip-hop. The Goethe-Institut and the German Historical Institute consider the relationship between the Berlin Wall and American artists in a new exhibition, “The Wall In Our Heads,” and a film series that runs through December. Tonight’s offering, Here We Come, chronicles the rise of East German b-boy culture through interviews with teenagers who adopted monikers like Magic Meyer and Beatschmidt and went on to perform on some of East Germany’s largest stages. Despite the thousands of miles between Berlin and Brooklyn, the cultural overlap ran deep. The film shows at 6:30 p.m. at Goethe-Institut Washington, 812 7th St. NW. $4–$7.
