I had a welding teacher that was always saying that he had read the dictionary twice. It felt like he was saying that as a way to show how he had a superior intelligence or something. It was pretty funny.
Looking at this my first thought was black sabbath but i don't know their songs enough. I did see war pigs in the black sabbath album when i was searching.
The image makes me think of some kind of "choir of the dead." So idk what your song is but i'll guess that. The robes and how they are lined up with the guy at the top behind a small desk makes me think of a choir.
They can't do better then perfection.
