“Which side are you on?” sings Florence Reece, an icon of the miners’ movement in Harlan County, Kentucky, with a brittle voice into the microphone at a union rally. Barbara Kopple’s long-term observation of the 1973 Brookside strike might even be called a music film. Because aside from Reece’s classic strike anthem, song and speech, folklore and politics, rhythms of speaking and editing are combined throughout: a successful attempt at partisanship that appeals to all the senses, where slogans are absent – or put into song. “Harlan County, USA” was presented in a special screening at the Leipzig Dokumentarfilmwoche in autumn 1977, its fame having preceded it: It had already won the Oscar for Best Documentary Film in April of that year.
