Recently, the Foo Fighters were playing a show, and Dave Grohl notices a fan in the front row holding up a sign announcing it was his birthday and that he played drums. Apparently, Dave and the boys wanted to see if he could hold his sticks with the Foos, so they got him on stage to play "Big Me."
Dave Grohl recorded the album almost entirely on his own as a way to deal with the death of Kurt Cobain, but it's been collectively all of ours for two decades.
