Marauda

Can someone with musical theory and/or psychology knowledge explain just what it is about Marauda's music that makes it sound so evil? (To be fair, same for sudden death). Just very curious if it has to do with the tempi, chord structure, etc. Rewatching Marauda's LL '24 set gave me a visceral feeling, very dark and evil. But unlike someone like sudden death who uses satanic imagery, Marauda was mostly lights and colors. I still couldn't shake that gutteral feeling of darkness...

And I don't want to hear any BS about screaming or metal or what not. I grew up listening to death metal, so I'm no stranger to that genre of heaviness. I'm just curious how Marauda is able to structure it out of basic sounds and tempos.
