An anthropologist and a soundmaker travel in Bulgaria in the pursuit of a socialist radio now disappearing. Through encounters, places, archives, they discover a whole sonic memory of communism, between nostalgia for a past society and rejection of a totalitarian power. What is left of radiotočka? What was its place in everyday life, its cultural imprint, its political impact? What did communism sound like? Through research-creation and extra-academic commitment, this inquiry also challenges the ways in which memory issues and production are addressed, in a context of growing political pressure on the storytelling of the past(s).
