We were travelling in outback Queensland recently and in the town of Winton there is an installation called ‘The Musical Fence’. The fence was constructed by percussionist Graeme Leak and there is also a drum kit made from old metal junk and various other percussive things to bang on. This sample was recorded on the iPhone. I might upload some other samples when we get home - they just need a bit of cleaning up as it was a bit windy there today. More about the Musical Fence here
