Aside from his stage name, heavy metal icon Ozzy Osbourne was also known as the music world's "Prince of Darkness." Here's how he got the nickname.

The heavy metal singer, who later became known for his reality show "The Osbournes," performed a retirement concert just three weeks ago.

The rocker helped define the sound, look and attitude of metal. But his persistence through addiction, his connection to audience and a late-career reality TV show endeared him to generations.

A tribute to the decade-spanning discography of the Black Sabbath frontman and first-name-only pop-cultural icon, who died this week at 76 after surviving enough metal madness to fill multiple lifetimes.

Ozzy Osbourne died at the age of 76 on Tuesday, weeks after Black Sabbath’s farewell concert. The “Prince of Darkness” died “surrounded by love,” according to a statement posted by Osbourne’s family on social media.
