Do I prefer Master of Puppets? Yes, definitely! Is this a good, heavy album? Hell yeah! This album is the one metalhead love to hate because that's when Metallica really reached mainstream success (even though they were already pretty big before that). But the truth is, it is a solid album. A bit long, but once again, solid and consistent.
Oddly enough this album opens with the classic Enter Sandman with a riff that is almost grunge (it was 1991, after all), but quickly settles down into familiar heavy metal territory with a heavy, doom laden song about being scared of nightmares. Apart from that, The Unforgiven plays with a spaghetti western vibe and Don’t Tread on Me gleefully nicks a riff from the song America from West Side Story. Metal-tastic!
