I've never had much interest in Alice Chains and this album doesn't do anything to convince me otherwise. Nostradamus by a mile.
Hammerfall have a lot of decent metal ingredients, and are fun on some level, but somehow nothing really shines here, it's all just gets a bit generic and stays that way throughout. I can overlook Rainbow sounding so dated because they sound so much more original and the songwriting sounds so much more creative.
I don't mind Helloween but could could happily skip a good few tracks here. Borknagar have zero fluffy moments and fewer throwaway ones. Moody, and consistent without ever getting dull.
Papa Roach, as I thought, although I forgot how irritating the 'squeaky clean' version of Last Resort is - can't have the F word in there, shit, or any references to self harm or suicide. Which kind of removes a hell of a lot of lyrics. This took me on a major nostalgia kick. I very likely wouldn't have gone back to listening to rock or metal if it wasn't for the nu metal movement forcing guitar music back up to the edge of mainstream, (proper guitar music, that is, not insipid clowns like Coldplay) and this album is a great example, with tracks like Between Angels and Insects getting a lot of radio attention. WASP are pretty decent too, but there's no way The Headless Children has made anything like the impression on me that Infest did.
