I don’t even know what made me think of this nugget from the past, but I just blasted it and it holds up pretty well.

In simpler terms, Black Sabbath sang about witches and Blue Oyster Cult sang about Wizards. Black Sabbath was about the depths of hell, Blue Oyster Cult was about black holes. More after the jump.
