"Until It Sleeps" is a song by American heavy metal band Metallica, released on May 20, 1996, as the lead single from their sixth studio album Load.

The band can be heard saying "Fell on Black Days" on the fanclub-only Fancan 1 CD just prior to jamming on a portion of "Until It Sleeps".

[3] "Until It Sleeps" became the first "officially" pirated MP3 when it was released by Compress 'Da Audio (a piracy group and spinoff of the Warez scene) via an Internet Relay Chat network on August 10, 1996.

The song also has a music video directed by Samuel Bayer (Nirvana, Green Day, The Smashing Pumpkins).

Apart from the general forms inspired from Bosch's paintings, the prominent figures in the video are the human-eating monster from The Garden of Earthly Delights, the fall of Adam and Eve from Haywain and Christ in the Crucifige Eum (Crucify Him) scene of Ecce Homo.
