I wear an open bottom girdle on a daily basis. All my girdles have metal quot;boningquot;. Is this enough metal to set off an airport metal detector?
Those aren't even real genres imo, they're sort of a combination between folk and melo-death with strict lyrical themes - like pirate metal bands aren't allowed to sing about anything other than pirates. but I guess if you want genres like that there's troll metal (Finntroll, Trollfest), swamp metal like that other guy said (which is basically just Kalmah), and I can't really think of anything else.. oh yeah, and Turisas calls themselves battle metal , not medieval metal...
1. Decapitated 2. 3. Goatwhore 4. Emperor 5. Isis? 6. Nile 7. Ale Storm? 8. Iced Earth 9. 10. Immortal
I think of both Viking Metal and Pirate Metal as both parts of Folk Metal that has an added gimmick to it, I don't see it as separate genres/subgenres.
Different genres? Well in terms of getting away from the traditional 'Heavy Metal' sound forged by the metal bands of the 70/80s, yeah, there are tonnes of genres. Doom Metal is slower and thicker in sound than Heavy Metal. This branches out into Funeral Doom, which is really really slow and atmospheric. Then there is Sludge metal, which contains elements of hardcore, such as the vocals but utilizes the thick distorted sound in Doom Metal but takes it to an extreme level. Then there is Power and Symphonic Metal which is awesome but it is milder to the traditional metal sound, and often uses a vocalist which sings at higher pitches than other metal vocalists. It also uses some of the esoteric instruments used in Folk/Viking Metal such as keyboard, piano or even flute and full-on symphonies. Black Metal and Death Metal have taken on many different forms from the Melodic, to the Atmospheric, to the Brutal. There are many different genres for many different tastes of music. It is a very rewarding genre and there are lots of different genres.
