"The Day The World Went Away" by Nine Inch Nails. The footage is from the Internet Archive (Public Domain) and is of a cold war test of an atomic bomb and didn't originally include sound.

The music used in this film is licensed by Universal Music Group. I uploaded this video to YouTube and the audio was immediately muted. FYI, I made this for fun. . . I don't profit from this video in any way other than amusement.

If any one knows what a-bomb test this was, let me know.
