It's difficult to define one of the most iconic careers in heavy metal and British rock 'n roll at large. The original lead singer of Black Sabbath, Ozzy embarked on a solo career in the early 1980s, culminating in an over 40-year-long career. Osbourne is a notable performer, known for his extreme behavior and wild attitude. He has ignited some controversy over the years due to the dark imagery and hardcore lifestyle represented in his music, but he remains revered by many for his contributions to heavy metal and rock 'n roll. In 2002, he premiered a reality show on MTV, The Osbournes, which became a runaway smash-hit, re-igniting his celebrity with a whole new generation of fans.
