It looks like an antenna that comes out from my head and goes up to the front of my face. At the back of my head there’s a chip which transforms the light waves into sound, and I hear the colours, not through my ears but through my bone.
At the beginning I had some strong headaches because of the constant input of sound, but after five weeks my brain adapted to it, and I started to relate music and real sound to colour.
I also started dreaming in colour.
It has changed the way I perceive art. Now I have created a completely new world where colour and sound are exactly the same thing. I like doing sound portraits – I get close to someone’s face, I take down the sound of the hair, the sounds of the skin, eyes and lips, and then I create a specific chord that relates to the face.
I’m starting a sound portrait gallery of famous faces which began with Prince Charles, who came to Dartington College of Art, where I was studying in 2005.
He asked me, “What’s this that you’re wearing?”, so I asked him if I could listen to his face, and he sounded very harmonic.
Some people might be very beautiful but they might not sound very harmonic, although harmony is subjective.
