This chapter maps out a set of anticolonial media poetics, politics, and aesthetics. It centres on a series of collaborative radio programmes produced in Athens, Greece, as part of ongoing work with an activist collective in the city. The chapter works with ideas of rhythm, relay, and relation – which serve both as methods and as guiding concepts – and narrates a form of citizen soundwork: sonic practices that experiment with geographical, political, and technological imaginations. This work in Athens is a convergence and continuation of media activisms elsewhere, carrying collective methods of voicing and articulating belonging across migratory contexts. And it sounds out anticolonial media activisms that feed back across histories and geographies of resistance and liberation. These media activisms unmake colonial hierarchies of voice and knowledge; and make anticolonial publics, communicating across radical sonic cartographies and building political cultures that contest the colonialities of borders and citizenship regimes.
