It's always neat when a fan gets to play with the band he loves. Imagine when the band is Queens of the Stone Age and the Fan is ex-Nirvana and current Foo Fighter fella Dave Grohl. Dave was supposed to play on three tracks for the new Queens album but it went so well he's ended up on nearly every song. Grohl said that it was "F***in amazing and rocks ten times harder than anything they've ever done." and that it was his favourite album he's ever drummed on.
