With a stellar electronic music resumé including work with The Byrds, Stevie Wonder and many others, Bernie Krause is assured a place in the pop culture canon. But Krause continues to make history by capturing the fading voices of nature: studying sonic interplay between species as they attract mates, hunt prey, and sound out their roles in the ecosystem.

Krause’s recordings are not merely travelogues or relaxation tools -- they are critical barometers of global environmental health. His documents of vanishing aural habitats are a chilling reminder of shrinking biodiversity. As he tells the Guardian: "The fragile weave of natural sound is being torn apart by our seemingly boundless need to conquer the environment rather than to find a way to abide in consonance with it."
