For a composer silence is something pregnant with expectation ... the most naturally spiritual medium. The music grows in the spiritual life: the silence of monks, the silence of meditation, the silence of not knowing something, the terrible silence of God when we are confronted with evil in the world. Music has always been intimately connected with the numinous and the immaterial. I increasingly believe that the non-corporeal quality of music can be a direct challenge to the world and its materiality.
