[on 'Snail's Law', a track on her album 'waterwall'] It's a play on 'Snell's Law' which is the formula that's used to describe the relationship between the angles and incidence of refraction. In that piece I attempted to do a musical portrayal of the refraction of light, so the music is presented in a straightforward way and then it starts to bend. And the way I did the bending is through the distortion of time: as the first part of the piece goes on, it distorts and some parts slow down. And of course other parts don't slow down, because with the refraction of light different frequencies refract at different times.
