Dio (band) has rocked out some great songs this decade as well
Just check out Eriel from Magica (2000).
I saw a Heaven & Hell concert a few months ago (Sabbath w/Dio) and the old man was still excellent. Lots of energy and while he's a bit tacky and weird in his videos, he still has lots of charisma and persona on the stage. I consider him a great man and one of the greatest voices in metal of course
