"World music" is an awkward phrase. Used to describe the hugely multifaceted nature of a range of, typically, non-English language popular musics from the world over, it's a tag that throws up as many problems as it does solutions.

Louise Gray's No-Nonsense Guide to World Music attempts to go behind the phrase to explore the reasons for the contemporary interest in world music: who listens to it and why? Through chapters that focus on specific areas of music, such as rembetika, fado, trance music and new folk, it explores the genres that have emerged from marginalized communities, music from conflict zones, and music as a form of escapism.
