A legendary farewell. Black Sabbath reunited for Ozzy Osbourne’s final show with the band at Villa Park in Birmingham on Saturday, and the electric concert featured performances by other rock legends.

Black Sabbath's farewell concert, which included hits like "Iron Man" and "War Pigs," comes as the rocker is living with Parkinson's disease.

Ask most music fans who “invented” heavy metal and they’d likely point you in one direction: Black Sabbath. The group’s self-titled debut album was recorded more than half a century ago, in – according to guitarist Tony Iommi – a single day in 1969.
