Foo Fighters frontman Dave Grohl insisted in a recent interview that the band’s latest recording sessions were disturbed by ghosts, per NME.

In a new interview with MOJO, Grohl and the rest of the band discussed the recording process for their upcoming album, which included sequestering themselves in a house built in the 1940s in Encino, CA. Despite the fact that Grohl sensed a disturbance almost immediately, him and the rest of the band were adamant that they record the album there.

“When we walked into the house in Encino, I knew the vibes were definitely off but the sound was f*cking on,” Grohl said. “We started working there and it wasn’t long before things started happening. We would come back to the studio the next day and all of the guitars would be detuned.”

Let’s assume that, as a working musician, Grohl is fully aware of the effects a drafty house from the 1940s can have on a guitar. The paranormal activity wasn’t just limited to the physical instruments, however, as the spirits used their technological knowledge to sabotage the sessions, Grohl maintained.

“Or the setting we’d put on the board, all of them had gone back to zero. We would open up a Pro Tools session and tracks would be missing,” Grohl said. “There were some tracks that were put on there that we didn’t put on there. But just like weird open mic noises. Nobody playing an instrument or anything like that, just an open mic recording a room. And we’d f*cking zero in on sounds within that. And we didn’t hear any voices or anything really decipherable. But something was happening.”

At one point, Grohl decided to set up a nanny cam that he had from when his children were younger. At this point, Grohl was still unsure if these anomalies were the result of human error or perhaps some mischievous malcontents in the area.

“At first, nothing,” Grohl said. “And right around the time we thought we were ridiculous and we were out of our minds, we started to see things on the nest cam that we couldn’t explain. Then when we found out about the history of the house, I had to sign a f*cking non-disclosure agreement with the landlord because he’s trying to sell the place. So, I can’t give away what happened there in the past but these multiple occurrences over a short period of time made us finish the album as quickly as we could.”

Thus, the mystery of the haunted Foo Fighters sessions is closed forever, or at least until this unspecified house in Encino is sold to some unsuspecting young couple. In spite of ectoplasmic interference, Grohl confirmed last month that the new album was finished but refrained from specifying a release date. Meanwhile, the band was forced to postpone its 25th anniversary Van Tour amid coronavirus concerns, albeit using Grohl’s perpetually-upbeat tone. Stay tuned to the band’s website for more information on the album’s release.
