Reviewers Jack Murray and Connur Joyce have both stated their belief that "Tomb of the Mutilated" is a high-concept album concerned with extreme necrophilia and sadism. Murray said "It's a very clever idea concerning the rape and murder of a young girl with a large knife, and continuing to rape the corpse until orgasm. This theme is particularly present in the last four tracks on the album", while Joyce announced in Finnish metal magazine "Mutilate", "The album has heavy connotations throughout. It's definitely linked; especially in the last three tracks. The explicit nature in which Barnes grunts his way through the increasingly morbid lyrics certainly demonstrates the theme running through the album, that is to say the increasingly deteriorating mental state of the protagonist."
