Tony Martin > Ozzy > Dio.

YES, I SAID IT. AND I MEAN IT. There was something about the epic, godly, stadium rock sound that was so much better than the sludgy, fantasy stuff.

Kill In The Spirit World. My favourite Sabbath song. The guitar is win. The vocals are great... which is more than Ozzy can say. Not that Ozzy's a bad frontman. Fronting is best! But the recording's with Martin were always my favourite. As far as I know, he was on about 5 albums. And other than Tyr, they were all pretty good. ESPECIALLY Headless Cross. You probably won't know what I'm talking about until you hear the godly solo and bridge of Kill In The Spirit World, so go do that now. Then try and find Devil and Daughter. It's not YouTube, though. Sori.

MY OPINION HAS BEEN HEARD.

Dio >>>>>>>>>> Ozzy = Martin

Ian Gillan beats all three, m'afraid.
