This interactive map was created by Thomson Holidays, a British travel company, as a guide for music tourists. The infographic traces the development of Western dance music. You'll note that the evolutionary tree branches into dance music with the advent of funk and disco and, after 1970, the visual explodes with new genres that emerge from the confluence of musical styles across the globe.
You can watch it unfold (all in about 15 seconds) or drag the counter back and forth to follow the interactions between genres more closely. BP
