It is just amazing what you can find at the back of the (electronic) filing cabinet. We’ve just turned up a ‘Dio: Roots and Branches’ Rock Family Tree, not seen since 1986 when it accompanied a 12in single. It hasn’t been published before, and so we have just made it available in our series of limited edition Rock Family Trees. View all the details, tracing his career from 1970 to 1986, in Deep Zoom here.
