Daito Manabe is a Japanese electronic artist/musician utilising his body work as an interactive platform to create his musical performances. In this video he uses electric stimulation of his facial muscles to trigger a midi sequencer and create facial muscular music (here is a link to his youtube video archive).
I like the way his physiological make up (the structure of his face) becomes a framework for his expression based performance. In parasitically hosting off a predefined system (in this case, a soft/wet system) we get adaption in progressive terms. This approach creates new experiences and also provides methodological thinking as a spur for innovation.
