I remember reading an old modern drummer issue years back when someone "gripped" at the notion of Dave Grohl being on the cover....Dave is actually a very competent drummer and over all musician...he has the ability to lay down some seriously heavy beats and never once does he step over his boundries in a song writing context...for all the "ney-sayers" out there just listen to "Everlong" or some of the QOTSA stuff or any Nirvana stuff...the guy can sing, play guitar, and is asked to play drums for just about everyone out there.... including Tom Petty......hats off to ya Dave!
