Max Cavalera had announced, this new project would be influenced by the kind Grindcore (pseudo-similarity perhaps debatable), but "Pandemonium" is intentionally not very worked at the production level, the two brothers wishing to render homage to their first loves and crados albums that have rocked their teens. Max was also amused doctored his voice in the studio, by superimposed layers, making them very serious and cavernous voice of 70% of the album. (We like the principle or you do not like), while Iggor has abandoned his groove for quick and brutal bastonnage.
"Pandemonium" is a gaming era for the two artists. Brutal, simple and effective.
