^^ lol, you haven't listened to much metal? (@ Dead Winter... Gojira isn't the heaviest band around)
Anyway, listen to these:
Korpiklaani - Folk metal à la finntroll. Only more beer-drinking inducing
Keep of Kalessin - Very fast thrash/black metal. Satyricon members playing here. Frost drummed for them too
Tankard - Excellent and underrated thrash metal band.
Stormlord - Over the top death metal with a lot of synchs and lots of riffing. Even though this may sound unattractive, you can't help but like this band.
Of course they aren't the heaviest band around...I'd say Nile or Necrophagist are in that realm, but Gojira is the first band in ages that I'm really excited about. A little Morbid Angel and some Meshuggah and there you have it. The reason I like them so much is because they are different than most other death metal bands. Nile, Behemoth, and now Gojira are really the only "brutal" death metal bands that I listen to (although Gojira isn't really that brutal) due to the fact that all the others sound the same and Nile and Behemoth are the only ones that have anything interesting to say. There are thousands of death metal bands who are just a carbon copy of something else, which is why I choose to listen only to the best, the cream of the crop. Gojira is the first band in ages that understands that hooks in death metal are actually a good thing, and that's what I meant by heaviness. Just because someone tunes to drop A doesn't mean they're heavier. Why don't we just get a 20 string guitar and have a contest on who's heavier, and the winner gets the crown by finding the lowest tone? Heaviness (IMO) is how it makes you feel, not if someone's faster or tuned down further.
Tankard is a way underrated thrash metal band...the Beauty and the Beer. Get it.
Seen Korpiklaani last year...nice guys, folk beer metal. Funny, too.
Check out Steel Attack...heavy/power metal with a Ripper Owens-like singer. Great songs.
The new Dimmu is not bad, don't listen to what all the elitists say. Good riffs in there, too. Not as good as others, but definitely not a waste of money. All the elitists I think are still waiting for their "tr00, nekr0, and gr1m prize" in the mailbox from bands who don't know or care who they are.
Agalloch is another great band, check them out too.
Anaal Nathrakh...bleak, raw, fast, and hateful black/thrash with a touch of death. If Emperor had a rabid dog, that dog would be Anaal Nathrakh. Some passages are similar to Emperor around IX Equilibrium. New album is more brutal, less black than Domine Non Es Dignus.
Bloodbath...check out both lineups with Mike Ackerfeldt and Peter Tatgren singing. Peter came after Mike. Good, brutal, easy to get into death metal. Very accessible to the death metalhead.
Billy Squier - the album Don't Say No...kicks off with an awesome song called In the Dark. It's not metal, not even close. Came out in 1982. You may hate it, you may love it. I've been listening since 1982 when I was 4 years old. Just good, driving classic rock.
