Ah, this is the damn album I have been waiting for from Metallica. Unlike St. Anger, this album IS a Thrash Metal record and in my opinion it is definitely on par with what the other old school bands like Overkill and Testament are releasing these days. It's time to get that Metallica T-shirt out of the cupboard again. Don't download this album. Go out and fucking buy it because they deserve it.
Maybe these videos will get you interested
If I were to buy albums based on the art on the sleeve, I will probably be owning a lot of Indie shit.
Anyway here's an interesting list of album sleeves.
