If you’re going to turn a song into a movie, you might as well adapt one that’s damn near feature length in its own right. That’s precisely what Radar Pictures is doing, Deadline reports today, as the company is planning on turning the 29-minute Karn Evil 9 into a sci-fi movie.

The Emerson, Lake & Palmer song appeared on the album Brain Salad Surgery, and it’s a 3-part story that tells of war between humans and computers in a post-apocalyptic world.

“Centered on a society that has drained all its blood with a dependence on technology, the film will explore the world controlled by a pervasive and dictatorial technocracy. The annual “Karn Evil” — a macabre rite of passage — is a young person’s once-in-a-lifetime chance to experience unbridled freedom, before subjugating themselves to the ruling class. When people stop returning from their Karn Evil experience, fear drives a revolution to topple the status quo and the artificial intelligence discovered at its heart.”

Writer Daniel H. Wilson is on board to adapt the song.

Notably, Brain Salad Surgery featured cover art from H.R. Giger (Alien).
