You can hear a collaboration between Radiohead and Hans Zimmer (via Bleeding Fingers) as the backing track for this long teaser for Planet Earth: Blue Planet II, the next upcoming showcase for the BBC's phenomenal chops in nature cinematography. With the camera climbing and diving above and below the surface of the water, the new footage is every bit as jaw-dropping as anything that's come before. (Unfortunately, the YouTube preview is only streaming in HD resolution.)
