Dave Grohl Says Foo Fighters Are Taking a Break

NEW YORK - Dave Grohl says his band Foo Fighters is officially taking a break.

Grohl sent an open letter Tuesday calling the band "my life," but noting "it's a good thing for all of us to go away for a while."

Grohl told fans Saturday at the Global Citizen Festival he didn't know when the band would play together again. He affirmed that in the letter.

He created Foo Fighters in 1994 after his time as the drummer in Nirvana. The band has been one of rock `n' roll's most enduring critical and commercial successes, winning 11 Grammys, including five earlier this year.

Grohl says he's now focused on his forthcoming Sound City documentary and album.
