Choreography of Sound concert

A week or so ago I went with friends to a concert put on for the International Mozart Festival by the Goethe Institute. It was held in an area of town that I've never ventured to before, in an old warehouse called King Kong - named after the huge papier mache gorilla looming over the space where the concert was held.

I was kind of expecting Mozart, but I couldn't have been more wrong. Described as an exploration of sound and music-making led by experimentalist musician Carlo Mombelli, it was performed on instruments as diverse as pick-ax heads, ladders and barber's scissors to more conventional guitars, voice and drums, to an Apple Mac.

Most of the music I found brilliantly mesmerising, haunting and beautiful, but I have to admit the sounds emerging from the Mac (once I'd worked out that the mild looking fellow behind it was responsible) were just weird, loud and discordant to my ears. The audience seemed to be entranced though, so I sketched some of them and let my pencil move expressively around their heads - a graphic representation of the music. Can you hear it ?
