The album is completely vicious; each track is a different representation of how Max Cavalera still has tricks up his sleeve. Not a single song blends together with the last or the next and each of which has its shining moments (the groove in American Steel, the numerous melodies in Gladiator). This album came as the biggest surprise, especially since I wasn't a fan of Omen at all.
Their heaviest and most technical album since Dark Ages, and very fast. Really enjoyed this, has a bit of old school Sepultura in there, and Soulfly have added a more death metal element, keeping the music fresh. A big step up from the mediocre "Omen", although I find the a lot of the songs have a weak ending, which lets them down slightly.
