Worldbeat

In popular music, worldbeat refers to any style of music which fuses folk music, often from non-traditional sources (essentially, outside the Appalachian folk and Celtic traditions) with Western rock or other pop influences.

Worldbeat is usually said to have begun in the mid-1980s when artists like David Byrne, Peter Gabriel, and Paul Simon began incorporating influences from around the world, especially Africa and Latin America. Within a few years, worldbeat became a thriving subgenre of popular music that influenced many more mainstream musicians. Some of the most commonly incorporated types of folk music include rai, samba, flamenco, tango, qawwali, highlife and raga.
