Dave spoke to Spinner about the reasons for the hiatus:
I think, to me, the most important thing was to give the audience a break from the band, not even that we need to stop playing, I feel like the world doesn't need another Foo Fighters record right now."
You have to consider a place like this, our studio, where when we come in here to do stuff it doesn't seem like much has changed," he says. "We might have nicer equipment, we might have a bigger set list, but honestly, it seems like everything around the band has changed in the last 15 years.
Outside of a few things, the way we work is still exactly the same because we never went into making an album feeling like we were the greatest, biggest rock band in the history of music. We've always felt like the underdogs. Going into make a record, I think it's important to feel like you're making your first record or you're the underdog because I never felt like we can just rely on the name of the band. There's no way. We have to actually try.
