Well I must say that I don't know why you've created this thread then. Why didn't you just start a Ronnie James Dio thread and talk about his music in that? You've literally called the thread The Creators Of Metal - Black Sabbath and you are avoiding the line up of the band that actually did what you are talking about. The RJD era of Sabbath did not create metal. As I said before, by the time Ronnie joined the band in 1979 or 80 metal was already going strong. Priest had released five or six albums, Maiden had just begun, UFO had been going for ages, AC/DC were at their peak, The Scorpions had a few albums out, the list goes on. The albums that created metal were the first three Sabbath albums, self titled, Paranoid and Master Of Reality in 1970 and 71. Honestly, Black Sabbath is only Black Sabbath with Ozzy. With Dio the name is the same but the band and the music is completely different. Awesome heavy metal music but it's a completely different sound to the original Sabbath that created metal. I think the band realised this when they got back together with Dio and changed the name to Heaven And Hell. They understood that if they called it Black Sabbath people would be expecting to hear War Pigs, Sweet Leaf and Paranoid etc, because that's what Sabbath is.
