Dave Grohl believes that ghosts interfered with the recording of the new Foo Fighters album.

He told Mojo that they went to to a 1940s house in Encino, California to work on the project, but thought something was weird from the start. He explained, “When we walked into the house in Encino, I knew the vibes were definitely off but the sound was on. 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. 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.”

The band eventually set up a baby monitor to capture what might be going on. Grohl said, “At first, nothing. 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.”

Unfortunately for fans of ghosts, he can’t reveal more. “Then when we found out about the history of the house, I had to sign a 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.”
