Black Sabbath

Despite its defiant title, this album hammered a final nail in the original group's coffin.

There was reason for excitement, given the band's resurrection behind Ozzy Osbourne's first replacement, Ronnie James Dio.

For once, even the harshest of critics and most devoted of fans were in agreement.

Though boasting another name, this band featured the heavy-metal godfathers' second-most celebrated lineup.

It was a stunning decision, one that hit the singer like a ton of bricks.

This should have been a cause for celebration of the fact that it coincided with their 20th anniversary.

A solid reputation fronting Rainbow and the underrated Elf obviously preceded him.

By this point, their inability to retain a lead singer had become something of a comedy of errors.
