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.

Ozzy Osbourne, the “prince of darkness” and godfather of heavy metal, has died aged 76, just weeks after he reunited with Black Sabbath bandmates for a farewell concert in his hometown of Birmingham in England.

A year later, they'd slimmed down, found a new name and invented heavy metal. Few bands are so inextricably linked with a musical genre, but Sabbath set the template for everyone from Motörhead and AC/DC to Metallica and Guns 'n' Roses.
