The line diagram

Each member is a lane on the year axis, in the colour of the line the band was on. A filled station marks a joining, an open one a departure, a square a death. The dotted rail is a reunion. A dotted branch leads to a band that grew out of this one, or in from a band its members came from. The table below lists the same spells.

The lines

  1. Hard rock1968 to 1970

    Earth, then Black Sabbath

    Four from Aston in Birmingham, playing blues as Earth in 1968, renamed after a horror film in 1969. The first album was recorded in a day in late 1969.

  2. Heavy metal1970 to 2017

    Paranoid to the final show

    Paranoid in 1970 set the template for heavy metal. Ozzy Osbourne was sacked in 1979 and Ronnie James Dio sang Heaven and Hell; a long revolving door followed, with Ian Gillan, Glenn Hughes and Tony Martin at the microphone and Tony Iommi the one constant. The originals reunited in 1997, made 13 in 2013 and ended the touring band in 2017. The last show, in Birmingham on 5 July 2025, was seventeen days before Osbourne died.
