Black Sabbath's album "Paranoid" was originally going to be titled "War Pigs", which would explain the man in a pig mask with a sword on the cover of it. The record label claimed it was too "Satanist" and that their song with the same name would be a great single. So alas, Paranoid was born.
Black Sabbath is the infamous band that is credited with creating the genre of heavy metal in the late 1960s' They were most known for their gothic themes, horror-inspired lyrics, and down-tuned guitars. The lead singer of the first couple of albums was Ozzy Osbourne, but after excessive substance abuse, he was replaced by Dio. They toured the world for over 45 years and are still a well-known and loved band today.
