Answers: The Wizard "The Wizard" is the second track of Black Sabbath's 1970 debut album Black Sabbath.

Sources claim it is about the band's drug dealer at the time (and may be partly true), but bassist Geezer Butler claims the character Gandalf from The Lord of the Rings as his inspiration.

"The Wizard" was a favorite of the band, and was later included on compilation albums
