Prince of Darkness, Godfather of Heavy Metal, simply, Ozzy Osbourne.
Ozzy has had one hell of career, selling over 100 million records worldwide as a combination of his fruitful solo career and as part of one of the Greatest Metal Bands of all time, Black Sabbath. He's toured with Iron Maiden, been inducted into the Rock and Roll Hall of Fame and has seen the rise of the family reality show with his MTV hit 'The Osbournes' in the early 2000s. Of course, Osbourne is notorious for a variety of other antics from biting the heads off of doves and bats to his infamous drug abuse.
Today, Osbourne stands as a heavily decorated musician with several awards to his name, including a Grammy, the NME Award for Godlike Genius, and Living Legend by the Classic Rock Roll of Honour Awards.
