Foo Fighters haven't made a good Album since Wasting Light, and half of that album sucked.
To be real blunt though, they were never the same after the first One by One sessions, which were leaked a few years ago as The Million Dollar Demos. They were angry, burnt out and bitter with each other, ready to break up. You can hear it in the recordings (probably why I like the "Demos" far more than that forgettable album). They took a break after hating what they did, came back after a year or so and recorded that piece of over-processed shit.
I hear far more good about Grohl than I do bad, so I don't have a problem with him. But the band is very overrated, so of course Prancin' Point Pat would want them to play his "end of White Heat" death. Top of the world, Mama Raven!
