“Heaven and Hell” is the title track to Black Sabbath’s ninth studio album of the same name. The music was written mainly by Tony Iommi, but as with almost all Black Sabbath albums, credit is given to the entire band. The lyrics were written entirely by then-newcomer Ronnie James Dio. The song has been performed by several bands of which Iommi and Dio were members including Black Sabbath, Dio, and Heaven & Hell. In an interview for VH1’s “Heavy: The Story of Metal,” Dio stated that the song is about the ability of each human being to choose between doing good and doing evil, essentially that each person has “heaven and hell” inside themselves. When the song has been performed live by Black Sabbath, Dio or Heaven & Hell, it’s usually stretched out with an extended guitar solo, audience participation, ad-libbed lyrics, or additional lyrics regarding angelic and demonic apparitions and personal judgment.
