‘Diaspora’ explores the effect of human displacement on world music after the ‘discovery’ of the New World by Columbus in 1492, which set off a chain of diasporas. The music of diaspora addresses both place and homelessness, wandering and the dream of return. Three diasporas are investigated, beginning with the Sephardic diaspora, which arose in turn from the expulsion of Jews from Europe; the displacement of Africans resulting from colonial slave trade; and the South Asian diaspora, which draws upon music to represent the post-colonial world. Diasporic music is diverse, including reggae, klezmer, bhangra, Bollywood, and hip-hop among other genres.
