This one is a little tricky. As the owner of the ultimate Heavy Metal vocal chords Ronnie James Dio has an overall career that could be considered Hall of Fame worthy. However, to the best of our knowledge, The Hall does not work this way. His 80’s band Dio, may have been his high water mark where his screeching vocals found a place as some of the most pure Heavy Metal of the decade. Ronnie James Dio is again the wildcard in the situation and although the overall performance of Dio may not be enough to get in the Hall they may feel that he personally warrants induction.
