As a synethaesiac, I find electronica very relaxing to listen to.
The sounds are very square, the colour consistent through each note. Easy.
It can occasionally become boring.
Then a band like Yazoo throws a singer with an amazing voice, full of passion and emotion, into the mix, making a beautiful picture of brightly coloured, strongly geometric shapes in the background and a wild streaming ribbon of varying colour, density and shape over the top of it.
One day, I will paint an image of what I see when I listen to a song.
The real challenge is that I can only paint one limited time segment, before the picture changes. Like flash photography, I would need to choose one tiny moment to capture.
And I would need to be able to remember what I saw.
