Aside from his stage name, heavy metal icon Ozzy Osbourne was also known as the music world's "Prince of Darkness." Here's how he got the nickname.

Ozzy's unique high pitched vocals stand out over the thick distorted guitar of Tony Iommi, meaty bass tone of Geezer Butler and thunderous drums of Bill Ward. Black Sabbath was a truly collaborative effort with all members involved in the songwriting process.
