Say what you will about the band (and I like them - they're consistently good, and occasionally spectacular), Dave Grohl is one of the coolest motherfuckers in the business. Even in a giant FF-emblazoned "throne" on rails moving forward and backward on the stage with his leg still up and in a cast, he was playing his ass off, and he just comes across as a guy who absolutely loves music and loves performing.
Such a cool show. The Foo Fighters killed it, the sound sucks in Fenway but that's not the point, and it was a gorgeous night. I didn't buy one, but they're selling t-shirts with the X-ray of his broken leg on it, which I think is fucking awesome.
