A sad day.. Another of my heroes has died. :( I first became aware of Ronnie James Dio’s incredible voice and interesting lyrics when Holy Diver became a hit in Sweden – this was back in the year of our lord 1983. I found out he had been the singer in Black Sabbath and Rainbow previously to his solo carrier. After a while I had bought all those albums as well. Inho, Black Sabbath’s Heaven and Hell and Mob Rules are two of the best heavy metal albums ever released.
