Black Sabbath - laguna sunrise, 1972

"Raise your hand if, somewhere around age sixteen, you went through a metal phase. Come on, admit it…you grew your hair out, you bought a ring with a skull on it, maybe even went to a Megadeth concert. Well, no matter what the details of your metal phase were, it probably included the basic principle that Ozzy Osbourne was God, and Black Sabbath was the precursor to every band worth listening to."
