Query: Great from beginning to end, the way it should be listened to!

All the tracks on this album are great!Tony Iommi is one of the top ten guitarists.If you or someone you know does not listen or has never heard Black Sabbath, get this cd.One of the heaviest albums of the decade (the 70's). I was a babywhen it was released. I may have not been born. I was born again, in my late teens, listening to Master Of Reality.Sweet Stuff!!
