Dave Grohl: Foo Fighters Are Definitely Taking A Break

If you're a Foo Fighters fan, Dave Grohl has confirmed the worst of news: The band is taking a serious hiatus.

Rumors started flying after Grohl told the crowd at Saturday's Global Citizen Festival that he didn't know when the band was "going to do it again." While many assumed Grohl was quietly announcing the end of the band, has made similar comments before.

In August, the singer had to walk back a similar statement he made at the Reading Festival, where he said that performance was "the last for a long time." (Grohl later said he was referring only to gigs in England).

This time, though, it seems like the band is dedicating themselves to other pursuits. Grohl's full letter is available below:

Hey everyone...

Dave here. Just wanted to write and thank you all again from the bottom of my heart for another incredible year. (Our 18th, to be exact!) We truly never could have done any of this without you...

Never in my wildest dreams did I think Foo Fighters would make it this far. I never thought we COULD make it this far, to be honest. There were times when I didn't think the band would survive. There were times when I wanted to give up. But... I can't give up this band. And I never will. Because it's not just a band to me. It's my life. It's my family. It's my world.

Yes... I was serious. I'm not sure when the Foo Fighters are going to play again. It feels strange to say that, but it's a good thing for all of us to go away for a while. It's one of the reasons we're still here. Make sense? I never want to NOT be in this band. So, sometimes it's good to just... put it back in the garage for a while...

But, no gold watches or vacations just yet... I'll be focusing all of my energy on finishing up my Sound City documentary film and album for worldwide release in the very near future. A year in the making, it could be the biggest, most important project I've ever worked on. Get ready... it's coming.

Me, Taylor, Nate, Pat, Chris, and Rami... I'm sure we'll all see you out there... somewhere...

Thank you, thank you, thank you...
