In my personal opinion, I think that Ronnie James Dio is a better frontman than Ozzy was, because he is a MUCH better singer. I love the songs "Turn up the Light" "The Sign of the Southern Cross" and "Country Girl". I like this album much better than any of Ozzies Sabbath work. The riffs are simply amazing, Toni Iommi knows his stuff.
I recommend this album to any rock or metal fan.
