BS was, as you said, too heavy for that time. That's why I'm talking about very limited musical impact that it did back in time.
Wtf do you mean? If they created a huge controversial stir, THAT'S impact. Whether it's negative or not, they had a huge impact on the rock music world.
Of course, people were trying to play as heavy as Iommi did. But as we know, it was not so easy for them and doom metal started for real about 12-15 years after release of Black Sabbath.
More like, doom metal started WITH the release of Black Sabbath.
Heavy metal from the other hand took its standards from Paranoid album which was faster and more acceptable than dark and evil BS.
Yeah that's pretty much my point. Paranoid was more accessible, more mainstream. But the impact of BS was just as huge, just in a different way.
Maybe Into the Void got thrash riff, Dissident Aggressor was influence to Slayer or Iron Maiden popularized punky style, but AoS was the big hit (which charted high) with harsh vocals, catchy, thrashy riff with shitloads of energy in the fastest tempo possible at that time.
Yes, it was much more popular than BS in their respective primes. So it wins popularity, but that's 1/3 of this criteria isnt it? Impact and influence is not even close and I cant even believe we're arguing this.
And it impacted speed, heavy and thrash metal directly. And immediately, which is the case. Many people think that Motorhead = Ace of Spades. I don't blame them. AoS is THAT big.
Speed, heavy and thrash metal? Nice try in attempting to make that sound like three different genres, or even sub-genres.
AoS impacted speed and thrash. BS impacted EVERYTHING in metal. You fail.
