I would definitely have to say Mob Rules too. A great solid album. They played quite a few songs from that album live too. Dio sang like he was 21. Didnt miss a note. Very impressive. Not to mention, Dio as well as Vinnie Appice the drummer, were such cool guys. I had the priveledge of hanging out with them til about 2am backstage after the show Wednesday, May 2nd.
