Dave Grohl is on a “March of the Insane” to get a new album released next week.

After quietly releasing the new thrash metal song this week in advance of the debut of his comedy-horror film Studio 666 on February 25th, Grohl said he is currently hard at work on an entire album, attributed to the fictional Dream Widow band from the film.

In the movie, Dream Widow is a band that went to a haunted mansion to record an album that was never released because the lead singer went berzerk and killed the entire band. But now the film version of the Foo Fighters are in that same creepy house 25 years later.

While the band uses Dream Widow’s studio to record their new Medicine at Midnight album, Grohl’s character finds demo tapes from this lost album, and by playing them, summons an evil entity, which the band must fight, presumably.

Grohl tells Rolling Stone magazine that he’s working day and night to have the album ready by the film’s premiere. “I mean, I work fast, but f**k, this deadline is going to kill me,” he said. “Yes, I’ll get it out for the movie. By February 25th, there will be a Dream Widow record.”

The album won’t sound like a new FF album, though Grohl said that fans can expect to hear influences of some of his favorite ’80s metal bands in the new work. “You’ll hear a lot of those influences in “Lacrimus dei Ebrius,” which is a 13-minute metal epic performed in the film, “because for that song, I put maybe four or five of these sections together in this big, long thing. Some of it sounds like Trouble; some of it sounds like Corrosion of Conformity; some of it has a Kyuss vibe.”

Studio 666 hits theaters as a preview on Thursday, February 24th.
