Wow that sucks!!! I've seen Dio more than a few times since the 80's. He had the ultimate metal voice, and put on one hell of a concert!
He had so many killer songs........... I'm listening to "Man on the Silver Mountain" right now!
For those who want a great CD of some of Dios best songs, go out and get "DIO Stand up and Shout Anthology"
It has songs from when he was in a band called "ELF", Rainbow, Black Sabbath, and of course many of his Dio songs (29 songs total)
Rest in Peace Ronnie James Dio, thanks for the great music!
