Undeath metal (or Christian death metal) is a genre of heavy metal music that is stylistically closet to the sound of death metal, but those artists are either directly against satanism prevalent in death metal, even those artists lyrics are about rape & cannibalism, or promote Christianity in their lyrics and imagery.
