I def agree Gorgoroth is some twisted blisteringly fast black metal.
I would def not say they are state of the art (see Behemoth for that stuff).
Gorgortoh is a little rough around the edges...and the production on this album is ***, but if you like the heavy stuff like I do you can look past it.
Bodom is def a neo-classical death twister for sure.
Alexi is a sick guitar player and the band can def mix it up with some of the heaviest out there.
One band you must check out is Arch Enemy.
The Amott brothers are incredibly talented guitar players, and have written some of the slickest and sickest riffs in recent memory (Diva Satanica)
You must own Wages of Sin!!!!
Also check out a band called Behemoth......
Nergal and the boys new album Demigod is brutal and will
have you throwing stuff around your room....and worshipping Satan himself(lol)
If you like the dark, brooding stuff check out:
My Dying Bride and Katatonia
Katatonia reminds me alot of Opeth as well.
I even think Ackerfeld played on some of there earlier releases.
Opeth is def cool but IMO the songs are too long.
I always find myself loosing interest in them after 6 minutes and end up advancing to the next song.
No arguing with the fact that they are all accomplished musicians that write quality music, however, songs that last over 10 minutes can get tedious after a while. But hey thats why they make chocolate and vanilla.
I would describe Opeth as follows:
lush, atmospheric, acoustic interludes graced with understated clean vocals coupled with moments of unbridled,distorted,guttural vocals, mixed with a heavy does of distorted guitars and double bass drumming.
Worth a try if you dont mind the cookie monster growling type vocals.
Very unique band indeed.
Hidden Gem:
...And Oceans
If you can find their recent stuff...buy it.
