Query: Foo Fighters have done it again...

I was a fan of their first two albums from the continued grunge of the first album to the straight-up guitar rock of Colour and the Shape. To accurately yet simply define the sound produced on this CD, it has the rock/pop sound of Colour... and the angry grunge feel of the first one. Learn to Fly may be the best song they have ever done, as well as Stacked Actors, Generator, M.I.A. and Aurora. Some of the songs harken back to Nevermind in terms of pop rock. But the rest of the songs distinguish themselves WAY apart from Nirvana. The sound is awesome and the production is spiffy. Overall, one of the best CD's of the 90's and, without a doubt, the best rock album of the year. Brilliant! Dave Grohl has done it again.
