After raising eyebrows during the Foo Fighters' Global Citizen Festival set in New York City this past weekend, frontman Dave Grohl has confirmed the news we have all been dreading: the Foo Fighters are going on hiatus.

The Foos were one of the headliners at Saturday's (September 29) event in Central Park, joining Neil Young, the Black Keys and more. Grohl gave a vague message to the crowd saying how this might be the last time they witness the band perform on stage for awhile.

"We don't have any shows after this," Grohl told the audence. "This is where we play as many songs as we can in a short period of time, because, honestly, I don't know when we're gonna do it again."

Naturally, rumors began to surface that the Foo Fighters were going to break up. We have some good news and bad news about this. The good news is that the band is not breaking up. The bad news is that they're taking an extended break until further notice. As Rolling Stone reports, Grohl took to the Foo Fighters' official Facebook page to announce the news to fans. You can read his whole letter 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 . . .

Dave

Thankfully, I was able to see the Foo Fighters last year at the Palace of Auburn Hills while they were promoting their most recent album, Wasting Light. Are you bummed that the Foos are going on hiatus, or do you think they should lay low for awhile? Tell us below.
