This Earth Day — Tuesday April 22 — enjoy 24 hours of natural soundscapes from around California and the world by Bernie Krause and the team at Wild Sanctuary.

KALW is proud to be a station leading the way on climate consciousness. And this Earth Day, we're excited to continue our tradition of a nature takeover of our airwaves.

Tune in for 24 hours of natural sounds this Tuesday, April 22, beginning at midnight. You'll hear audio from around the world recorded by Sonoma-based soundscape ecologist Bernie Krause and his team from Wild Sanctuary, all introduced by members of KALW's team.

Earth Day is every day at KALW, but the nature takeover only comes once per year. We hope you enjoy it.
