“In [the dance style called] footwork, an individual, usually a boy, strides out into the centre of a group and starts jittering with his feet in fluid slides and taps, sometimes jabbing forwards to provoke an opponent. With the music usually played at aggressive tempos of 155-165 bpm, footwork is an exercise in speed. Dancers’ feet blur beneath their static torsos, keeping balance in hypnotic burst of rhythm.”
