someone could write an album about a rap star who gets possessed by demons and gives in to his urges for unholy behavior heedlessly like a brainless meat puppet.
they could star him in it and they wouldn't even need to take anymore scenes of him, just use outtakes from his other stuff because he looks like that already.
how does one write social commentary about someone who seems clearly possessed? Or he's doing a bit? No, how could it just be a bit.
there is little else to explain it. Seems like an exorcist would be useful. Does K perform them?
