Black Sabbath has been widely credited with defining and popularizing the sound of heavy metal — aggressive, but full of melodies. Osbourne was the band’s frontman during its peak period in the 1970s. His antics, on and off stage, were legendary, and often fueled by copious amounts of drinks and drugs. He was widely known as the “Prince of Darkness.” The band’s eponymous debut album in 1970 made the U.K. top 10 and paved the way for a string of hit albums, including 1971’s “Master of Reality” and “Vol. 4” a year later. It went on to become one of the most influential and successful metal bands of all time, selling more than 75 million albums worldwide. At the final show on July 5, 42,000 fans watched the band perform for the first time in 20 years at Villa Park, home of the city’s biggest soccer club, Aston Villa, with Osbourne seated on a black throne. Osbourne had been in poor health in recent years, especially after being diagnosed with Parkinson’s disease in 2019. Osbourne, who also had a successful solo career, found a new legion of fans in the early 2000s reality show “The Osbournes” in which he starred alongside Sharon and two youngest children, Kelly and Jack.
