Tony Iommi is the lone member of Black Sabbath to appear on all 19 of the studio albums. In fact, 1986's Seventh Star was initially meant to be an Iommi solo record before last minute pressure from their label led it to being released under the Black Sabbath moniker.

Black Sabbath has announced plans for one final reunion performance in their hometown of Birmingham on July 5th.

The singer will play his own short set before the veteran heavy metal band play together for the first time in 20 years
