This thesis examines the experience of affective belonging in the grindcore music scene. Presenting an ethnography of how scene-members in Australia and Japan participate in grindcore, my thesis shows the experience of affective belonging in three ways: spatially, socially and through the transnational exchanges between both scenes. My thesis formulates the concept of ‘brutal belonging’ as a metaphor for the intense, sometimes violent, sensation(s) of affective belonging in grindcore, to argue that fans experience belonging via shared affective intensities rather than scenic signifiers. My thesis focuses on how grindcore metal music scene-members in Australia and Japan experience belonging affectively.
