As a guy who was never into the "metal" of the 70's and 80's, i wasnt the owner of any music in which Ronnie James Dio's classic vocals were featured. This did not prevent me from appreciating the legend that he was, in the music world. His had a voice that could overshadow the loudest guitars. It was the standard of the genre and few could compare.
It is a sad day in the rock world as we have lost this icon to cancer. I may not have been a fan in the strictest sense of the word but it was impossible for any musician not to understand his impact and his place among rock royalty.
Rest in Peace Mr Dio.
