I think we need to stop asking if there is any way that Dave Grohl can be cooler, because the answer will always be yes. Whether he's hanging in the GA pit watching Soundgarden, scaring the Westborogh Baptist Church, or most recently, providing backing music for Roger fucking Waters while he performs a Pink Floyd classic, there is no denying his cool. This performance was put together by the folks at Late Night with Jimmy Fallon, as part of "Pink Floyd week". Every day this week, there is a new performance of one of the band's classic tunes. You can catch up on all the clips right here, and especially make sure to check out this awesome Q&A with Roger Waters.
