I saw them play at Leeds Festival in August, in the NME tent. It was pretty special. I much prefer Dave Grohl on drums. My problem with the Foo's is that it's all rage - veins bulging from his neck and forehead, and lots of angst and shouting. But it's all fart and no shit. It's all a bit empty and meaningless.
But he's still an amazing drummer and one of the most friendly people in a band I have met.
Would love to see the supergroup again!
