In the book Precious Metal: Decibel Presents the Stories Behind 25 Extreme Metal Masterpieces
, the new Black Sabbath line-up talks about their impressions of each other before they worked together. Iommi says that he really loved Ronnie's voice when he listened to his work in Rainbow. Butler had barely heard one track. Ward mentions Rainbow's "Stargazer
" (from the 1976 Rising
album) as "an unbelievably good piece of work," and Dio had of course heard their singles on the radio but hadn't rushed out to buy any albums.
In the book, "Die Young" is specifically mentioned as having been written in Miami. The band was in transition from Bel Air California to Miami Florida, as well as transitioning between lead singers and having a new producer (Martin Birch) as well.
