Up until very recently, I faithfully observed a rule to avoid “all-time” lists where the name Ronnie James Dio appeared to the right of any integer below seven. This was, of course, before I encountered VH1’s 100 Most Metal Moments, in which Mr. “Holy Diver” himself is the subject of numbers three and one.

Seriously, did I miss something? When did someone who is best known these days for appearing in cartoon form at a South Park school dance become such a pivotal figure in music? Somebody clue me in please.
