Dave Grohl, Taylor Hawkins and keyboardist Rami Jaffee played at the Acoustic-4-a-Cure IV benefit concert in San Francisco last night. They decided to play a brand new tune they’re never played in front of anyone. The sound quality isn’t the best but it’s still rockin. I wonder what the studio version will sound like. The real question is…… Is this foreshadowing to a new Foo Fighters album?
