It seems like Dave Grohl really means it this time about a Foo Fighters hiatus: after telling audiences in England and New York City that they were seeing the last Foos shows for a long time, Grohl has now penned an open letter on behalf of the band which was posted online Tuesday (October 2nd). After thanking the fans "from the bottom of my heart" for "another incredible year," Grohl begins, "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."

But then he adds, "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 . . ."

However, Grohl next says that there are "no gold watches or vacations just yet," adding that he'll be focusing his energy on finishing his documentary and album about the legendary Los Angeles recording studio Sound City "for worldwide release in the very near future."

He states that the project has been a year in the making and "could be the biggest, most important project I've ever worked on. Get ready . . . it's coming."

Grohl then signs off on behalf of the rest of the band, saying, "I'm sure we'll all see you out there . . . somewhere . . . "

Grohl told us a while back that he is always looking to avoid getting into a rut, which could be one possible motive for a long break: "If you start feeling stagnant, like you're doing the same thing over and over again, it just loses that excitement or that charm, you know. You don't want to feel like you're doing the same thing over and over and over again."

At the Global Citizen Festival this past weekend in New York's Central Park, Grohl said, "We don't have any shows after this. 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."

A representative for the band told MTV News that the Foos, now in their 18th year as a band, are "definitely not breaking up."
