Ozzy Osbourne, the legendary singer of Black Sabbath, passed away on Tuesday night aged 76. It's an emotional end to an era that transformed not just how rock music sounded, but how it looked.
The band known to fans simply as "Sabbath" is best known for inventing the doom-laden sound of heavy metal by down-tuning their guitars. But their equally important contribution to rock's visual identity often goes unnoticed.
