when I first came to know Metallica it was 1988, when I bought the cassette (in my small village you could only buy cassettes at the time) of Justice. I was immediately knocked out by Blackened (and maybe I never recovered). after this album I bought almost everything I could find about them and therefore I learned a lot to say that this album is the peak of their production. In my opinion it mingles strength, power, rage, technique, melody, aggression, superb songwriting like no other Metallica album. maybe it is not their best but for me it's the most complete of their career. after Justice there are some good things but you can hear that a slow decline begins from the Black album onwards. They are still one of the greatest live acts, in my opinion they already experimented everything in their possibilities and they should remain just a live band... but obviously they sell for millions and so they will continue with studio albums. At least in Death Magnetic there are some awakening signals (after more or less 20 years of bad sleep). In the end Justice is beatiful in each of its parts and still kicks when I play that old cassette.
