Seriously, what doesn't this song have? Fucking awesome riffing, technical ability everywhere, great drumming, Mustaine at his peak and Marty laying down ridiculously technical leads that fit the song perfectly, all with bad fucking ass lyrics over it.
For non-musicians, it's just an asskicker of a song. For guitarists, it's pretty much the benchmark for thrash rhythm playing. It's technical as hell without sacrificing the song structure for the sake of being technical, and you need both a monster picking and fretting hand to pull it off. Not to mention that the album mix is fucking awesome (though this YT video is shitting on it).
This album is right up there with ITP/Symbolic for being the high water mark for the genre. Say what you will about Mustaine these days, but if you write this album you can do whatever the fuck you want if you ask me.
I couldn't agree with more my friend. Its the stuff dreams are made of.
