The label say: "Cavalera brothers Max and Igor delude nobody when it comes to determination and stubbornness. Pandemonium is no exception - frontman Max rushes with a bellow of rage into the fray, lets his brother drum the coarsest grooves, and puts his finger into the open wound."

Max recently described the work as "very, very heavy - the heaviest of all three" and added: "I was really possessed to get Igor back to his Arise era of drumming, everything fast."
