"Humanity Still Producing New Art As Though Megadeth’s ‘Rust In Peace’ Doesn’t Already Exist" - The Onion, August 3rd, 2015
(I recognize I'm not original in referencing The Onion article, but its honestly the best review of the album and while I'll add my thoughts, they're honestly pointless when that article exists)
That headline is a joke, but it's honestly not far from the truth. Rust in Peace really is close to the pinnacle of thrash metal from the 80's. In my mind, the only albums competing with it are ...And Justice For All, Reign in Blood, and maybe Master of Puppets (I'll have to listen to it again, but I remember thinking the second half of the album did fall in quality), with Reign in Blood being the only one that actually gives it a run for it's money in my opinion.
Of course, there are other great thrash bands like Coroner but they never got big enough to be on the same level with the likes of a Megadeth, Metallica, Slayer, and Anthrax.
But yeah, this album is just a riff and solo machine. Trying to find another album that comes even close to this thing off the top of my head feels like a fool's endeavor. Every song just crushes, particularly stuff like Holy Wars...The Punishment Due, Hangar 18, Lucretia, Tornado of Souls, and Rust in Peace...Polaris (Which is 2/3 of the track list, and the other 1/3 is still great). The soloing on songs like Holy Wars, Hangar 18, and Tornado of Souls is close second to none, every riff is a winner, the drumming is frantic but great. It's just insane.
And while Dave Mustaine isn't the greatest singer, his nasally, high pitched tone works extremely well with the music and lyrical topics (Usually conspiracies, politics, and whatnot). And the album is just damn fun compared to Slayer's ultra serious-ness and Metallica's more every-man blandness (And I don't necessarily say that as a dig at them. It works well for them. They're the Mario of thrash metal).
Just an all around masterpiece of the thrash genre. Honestly might be my favorite thrash album, but at the absolute worst, it's top 3, and it's not close.
