I believe you might be confusing two different bands. Mental Cruelty is a German deathcore band, whereas A Hill to Die Upon is an American blackened death metal band. Mental Cruelty has released the following albums: 1. Pereat Mundus (2018) 2. Inferis (2019) 3. A Hill to Ascend (2021) On the other hand, A Hill to Die Upon has released these albums: 1. Infinite Titanic Immortal (2009) 2. Omens (2011) 3. Holy Despair (2014) To provide an answer, I'll discuss Mental Cruelty's 3rd studio album, "A Hill to Ascend" (2021). This album incorporates themes surrounding war, violence, and nihilism. The lyrics use violent images and metaphors to portray the chaos and terror of these themes. Additionally, the album features a mix of deathcore and slam elements with fast, brutal, and heavy guitar riffs, pounding drums, and guttural vocals to create an atmosphere of aggression and brutality.
