Foo Fighters frontman Dave Grohl has sent an open letter to fans thanking them for all the support they've given the band over the last year and confirming his recent announcement that the band is going on an extended break now that they've wrapped up touring behind last year's 'Wasting Light' album.

"I'm not sure when the Foo Fighters are going to play again," Grohl writes in the letter, which was posted on the band's official website. "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."

Yes, that makes sense. After 18 years playing together on and off, the Foos certainly deserve a vacation -- and no, that extended break is not a break-up, as some speculated following Grohl's comments during a Foo Fighters gig in New York City over the weekend. "I can't give up this band," he promises in the note. "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."

And while it could very well be a long time until the Fighters hit the stage -- or even the studio -- together, Grohl isn't about to rest on his laurels. "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," he says of his short-term plans for his long-in-the-works flick about the legendary Van Nuys, Calif., recording facility of the same name.

"A year in the making, it could be the biggest, most important project I've ever worked on," he concludes. "Get ready... it's coming."
