This edition of At Water's Edge focuses on a core principle of ambient music: atmosphere or environment. Ambient music is a fascinating genre, in that it relies on subtleties and nearly imperceptible shifts to create an ... ahem... environment of listening that is immersive and moving. It is "equally listenable and ignorable" (Brian Eno's definition).

Unlike the music that we hear, our own environment, that of planet Earth, is in grave peril -- not ignorable at all. As humans, we have a challenge and a responsibility to preserve our environment, both for our own generations and for the flora and fauna with whom we share the planet. It is time to listen, and not ignore.
