Dio and Ozzy sang in two different Black Sabbath ages, and they were both great and suitable to cover the goal of singing that dark, strange, beautiful music.  They were other singers, too and I don´t reject any.
The band evolutioned, the singers too. Sabbath rules 4 ever
Found this in YOU TUBE
ELECTRIC SLEEP BLACK SABBATH
very bluesy
watch

Very valid point Nupe. However,Sabbath started in 1969 and while covering such tracks as Blue Swade Shoes ect...they also started jamin' the title debut track "Black Sabbath" and its just something about thier "image" too...

4 guys dressed in black wearing crosses singing about Satan,I know Deep Purple,Uriah Heep and the less known band "Black Widow"  and Pentagram(but they were too underground to make a difference)also contributed to the movement..ect..ect...

Its Black Sabbath that was a turning point that years later you can actually hear "metal" in thier riffs but very primitive. Also again with thier (back then) satanic image and doomsday approach,this is why  they "started it all" with metal,even though they didn't use the tearm 'metal" back then,years later we hear the song 'Black Sabbath" from 1970 written in 1969 with thier image and lyrics we can sense "metal" big time.

I can't say that about all the rest of the bands. I don't really hear "metal" in Deep purple,Uriah Heep,Pentagram,ect.... sure I get where your coming from with thier riffs ect...yes they belong in the movement but even though Deep Purple started BEFORE Black Sabbath they were nowhere near as heavy,doomsday-like or satanic orienated as Black Sabbath untill after Sabbath's debut they may of had a few tracks ect..but nowhere consistant as Sabbath was at these idiologies.

Again I can't stress enough the image and lyrics,there was just NO band before Black Sabbath that was the creators of heavy metal.

Venom holds the same torch for extreme metal as they created black,death,thrash and speed metal.Irritating or not I don't think in my opinion this is an "opinion" I think its fact if you put all the pieces to the puzzle together and analyze them all,but good points you've still brought up beings the other bands continued Sabbath's creations.

		While I usually try to avoid arguments over the internet (as I like being a diplomatic person, who supports neither side of some issues), I'd also like to add my two cents here. I'm particularly irritated by someone saying that Sabbath "started it all" and were "creators of metal". Yes, Sabbath was definitely one of the heaviest, if not the heaviest band in '70-'71, with a large credit going to Iommi's downtuned guitar. But there were also others that put out similarly heavy stuff in the same era, like Deep Purple or Uriah Heep. While most, including me, would nowadays agree that they're both more hard rock than metal (with Heep more on the progressive side), imagine being in 1970 and start playing In Rock or Very 'eavy, Very 'umble. Both have blistering first tracks in Speed King and Gypsy, and the whole Purple album is very heavy indeed (can't say the same for Heep's first effort: although the US version did have Bird of Prey in it as well, overall the songs are less heavier). Come '71, Sabbath would already have three very heavy albums under it's belt, while the title tracks to Purple's Fireball and Heep's Look at Yourself (Salisbury, released earlier that year was more progressive and only Bird of Prey and Time to Live could be considered "heavy") were blisteringly heavy at the time. After that, more and more heavy bands started to pop up, with the Priest lurking at the back as well...      J.D. DIAMOND wrote:   Very,very well said Jimmy. What you've said is ABSOLUTELY 100% correct.   Everything you've posted here is "true".  Also he should of created a Dio's Sabbath thread only because of his disliking for early Sabbath. He has every right to dislike the Ozzy years but creating a thread named The Creators of Metal and leaving out the Ozzy years is misleading.  On another note,I absolutely can't stand the album 'The Devil You Know",it spanks of poor song writting. A very big letdown for myself when I heard the LP and knew I wasn't going to buy it. I don't even like one song on it.      jimmyjames wrote:   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.      Brian_Evans wrote:       Ozzys voice is just too annoying man...lol      jimmyjames wrote:   One of the great underrated  Sabbath songs.

Ahh Jimmy, I do like you.
Quite possibly my favorite Sabbath song. Love "Megalomania" from that LP also.
