I was lucky to see Heaven & hell when they came to sydney in 2007. They were backed up by Down and it was only the 3rd time Dio played in Australia. I will always remembering singing along to Heaven & Hell that went for 20 minutes plus Vinnie Appice drum solo.
I have brought so many records with Dio on lead vocal and all of these records are something that you should have in your collection: Ritchie Blackmore's Rainbow, Rising, Long Live Rock and Roll, Heaven & Hell, Holy Diver, Dehumanizer etc
The Metal world remembers Ronnie James Dio for what he did to Heavy metal. By raising the horns he gave us an imaging and a symbol and of course you can sing very well and be a metal artist.
If you are visiting Los Angeles go leave some flowers at Ronnie's grave at Forrest Lawn Hollywood Hills.
