This edited volume concentrates on the period from the 1940s to the present, exploring how popular music forms such as blues, disco, reggae, hip hop, grime, metal and punk evolved and transformed as they traversed time and space. Within this framework, the collection traces how music and subcultures travel through, to and from democracies, autocracies and anocracies. The chosen approach is multidisciplinary and deliberately diverse. Using both archival sources and oral testimony from a wide variety of musicians, promoters, critics and members of the audience, contributors from a range of academic disciplines explore music and subcultural forms in countries across Asia, Europe, Oceania, North America and Africa. They investigate how far the meaning of music and associated subcultures change as they move from one context to another and consider whether they transcend or blur parameters of class, race, gender and sexuality.
