So what exactly would it sound like if you took the ever-memeable vocals from "Never Gonna Give You Up" by Rick Astley and placed them overtop "…And I Return To Nothingness" by Lorna Shore? Well, you get the most blackened Rickroll there has ever been, and one that actually sorta works a little bit.
Shout out to YouTuber lavagon64's Mashups for creating this monstrosity.
