Over the course of his storied music career, rock icon Ozzy Osbourne faced health battles with substance abuse and Parkinson's disease.

The gloomy, demon-invoking lead singer of the pioneering band Black Sabbath who became the throaty, growling voice of heavy metal, Ozzy Osbourne has died.

Osbourne's family says he was "surrounded by love" when he died, just weeks after his farewell gig in his hometown of Birmingham.
