I listened to this piece (recorded at the BBC proms in 2012) on the recommendation of a fellow student. It is written, rather unusually, for ‘body percussion’ – all sorts of sounds are used including clapping, knee slapping, finger snapping, humming, hissing and shouting. It’s almost as visual as it is acoustic; you can see the musical patterns by the motion of the musicians as they bend and gesture to produce the sounds. This is especially true towards the end when a wave is generated by the musicians passing along the sound/gesture to each other. The texture is built up slowly from unison clapping at the beginning, and with the help of some clever choreography I think it’s quite a fun piece.
