But dudes? Sabbath. Now I think Zeppelin has done a monuments work when it comes to modern music, but every time someone considers them metal, along with The Kinks, and Blue Cheer for that matter it just kind of makes me say "what are you on". Yes, you can probably find essence of metal in their music, but Black Sabbath found the sound and stuck to it for an album's length. An entire catalogs length when you think about it.
And okay. I get it. Sabbath doesn't have double-pedals or sweeps in their guitar solos. If you listened to this week's bombcast and heard Jeff's rant against people who hated Wind Waker only cause it wasn't mature then I can pretty much say the same for the folks that think that in order for things to be metal it has to have so and so. Sure. I believe bands needs to have certain aspects to achieve a "metal" sound, but when arguments like that are thrown to Sabbath it pretty comes down to them not having the fact that it was 1970 in mind. But even with that in mind you can probably argue that metal blast beats started when Black Sabbath did it for a couple of seconds in this video where Bill Ward goes nuts during the outro solo, but that's being nitpicky. lol
At the end of the day it's all subjective and boy, will it ever end? OP just wanted a list of what you all liked. And here I am. A little sad cause Black Sabbath gots no love. :3
