Lauren LaVera is back this year in director Joe Lam‘s indie The Fetus, a horror-comedy with a wild pregnancy horror premise. The film will have its streaming premiere on September 9, and while you wait we’re debuting the official prequel music video this afternoon.

It’s titled The Devil Inside, and it comes courtesy of independent metal band To Die For. The video for the officially licensed track features The Fetus co-star Evan Towell, and it serves as a prequel to the movie, expanding upon the world of the upcoming horror-comedy feature with Easter eggs that shed light on the significance of specific characters and events.

The collaboration between a horror film and a metal band creating music within the same universe is a nostalgic throwback to the early 2000s, echoing iconic pairings like Ghost Ship with Mudvayne, Resident Evil with Slipknot, Queen of the Damned with Deftones, and more.

“The collaboration with To Die For came from their genuine love for the film’s fresh take on horror,” says Lam. “They took the core storyline and reimagined it through their own creative musical process. When I first heard ‘The Devil Inside,’ I was completely blown away— and even more so after seeing the music video. It’s an honor to have artists inspired by my work expand The Fetus universe in a way that speaks to both horror and metalcore fans.”

“It’s very rare for an independent band to get the opportunity to do a music tie-in with a full-length film,” says vocalist Tyler Morris. “It’s even rarer for it to be a band that, at the time of the decision, hadn’t released anything publicly. But when you believe in something—and want to see it succeed—you take the chance. We believed in what the crew of The Fetus had done, and they believed in what we had to offer as well. That mutual respect, support, and admiration is invaluable, and our work together has created something far greater than we anticipated. We’re all very proud of what has been ‘birthed’ from this.”

To Die For features Tyler Morris (vocals), Matt Bolea (vocals), and Joseph Sauret (guitars, production). Music is mixed and mastered by Ricky Jabarin (guitarist of Taylor Acorn, Unsafe Unsound). The Devil Inside music video was filmed and edited by Travis Ilapit. Behind-the-scenes videography was filmed and edited by Hannah Lujbli.

Horror vet Bill Moseley (Texas Chainsaw Massacre 2, House of 1000 Corpses, The Devil’s Rejects) stars alongside Lauren LaVera in The Fetus, and the official trailer is also below.
