The aggressive rhythms and powerful guitar sounds of SLAYER are unmistakably present in "Diabolus In Musica". The album's title is particularly fitting, as the dark, minor key riffs and modalities that underpin the band's music serve as a sonic representation of evil and darkness, fostering an inescapable feeling of foreboding. The tracks, including "Bitter Peace" and "In The Name Of God", exemplify a streamlined metal style, containing only the crucial elements necessary to effectively deliver the band's message. A unique characteristic of the band's sound is that, despite the frantic delivery of Tom Araya's deep vocals, they remain clear and articulate, reflecting Slayer's concerns with political, social, and personal turmoil.
