This album in my opinion presents the best work from Sepultura. Chaotic and intricate in narrative, these songs make from simple riffs and pure noise an aura of evil that holds reality in suspense. Although some instrumentation is unsteady as a whole drumming and guitar work is creative and deliberate. Dramatic theming to songs make them unique, but raw spirit and concept is what draws these collections of power chords together. Riffs are of the faster Slayer-influenced style or in a minimalist muffled strumming rhythm playing form. Blasphemic lyrics tumble out in a death metal vocal of some sophistication considering the 1984-85 recording date on these albums. For those looking for a underground insight to the passion of this band, this album is great, but if Chaos A.D. is your thing pass it by.
