The experience of immersion rather than concentration forms one of the strongest links between modern and medieval man. But we can look back farther still to determine a common origin. Where then is the dark and fluid space from which such listening experiences spring? It is the ocean-womb of our first ancestors: the exaggerated echo and feedback effects of modern electronic and popular music re-create for us the echoing vaults, the dark depths of ocean.
