“The way they dance and move; it's like they don't have any bones!" said Richard ‘Nozinja’ Mthetwa, chief architect of the Shangaan electro sound, to the Guardian, the scene he engineered came to world attention in the late-2000s. There’s another word for their rippling manoeuvres: frantic. Mthetwa’s dancers have vigorously wound their waists to his break-neck beats – which have been known to go up to 190bpm – ever since he brought his synthesised version of traditional Shangaan music, with its synthesised marimbas and organ, to weekly street parties in 2005. One group, the Tshetsha Boys, don boiler suits and clown masks, like a parent-friendly Slipknot; female dancers tend to wear ruffled xibelani skirts that emphasise how quickly their hips swing around. Shangaan has a like-mind in Chicago footwork for its pace but also because the moves are considered just as important as the music.
