In South Africa there’s a style of dance music called Shangaan electro—named after the tribe whose musical tradition it’s based in—that uses maniacally fast tempos and hypnotically repetitive looping melodies to fuel a dance style that demands such speed and agility that, watching YouTube clips of it, you can have a hard time accepting that the footage hasn’t been sped up or tweaked in some way. Which is just about exactly the same way you’d describe Chicago footwork music.
