Its a London thing tells the story of the black music culture that emerged in post-colonial London at the end of the twentieth century; the people who made it, the racial and spatial politics of its development and change and the part it played in founding Londons precious, embattled multiculture. Melville explores the dance cultures of soul and reggae in the 1970s, rare groove and acid house in the 1980s and jungle and its off-shoots in the 1990s. The book argues that these demonstrate enough commonality to be seen as one musical continuum, and that the political and social importance of this form of popular art puts London firmly on the map as a global centre of this Afro-diasporic culture.
