Gorgoroth!
That is Norwegian Black Metal, which is slightly but significantly different than regular black metal.
The first batch of Black Metal bands included Venom (duh), Bathory, Hellhammer, Celtic Frost. Lyrics were generally laced with Satanism, gore, death and much bad stuff happening.
When the Norwegians claimed Black Metal for their own, in the early 1990s, they had a definite musical slant (classical symphonic music fused with hard rock) they started with, and by incorporating more music phrases and themes from Norwegian folk traditions, they fused these disparate elements into their own unique sound.
Moreover, their lyrical content was not necessarily Satanic, it was anti-Catholic. There is history of hundreds of years of oppression and submission of native Norwegian religion(s?) to Catholicism, since not everyone was happy with what went on after King Olav was killed in 1030. Also, they can lay claim to writing stuff about vikings, and it’s a known fact that writing about Vikings is always awesome, unless your name happens to by Yngwie J. Malmsteen.
They also brought the use of corpsepaint and spiky accessory wear to the forefront, everyone seeming to do their best to look like someone it would be inadvisable to hug or even get close to. Concerts in NBM are often very theatrical affairs, with lots of props and even many costume changes. The vocals in NBM are more CMV, too; you usually don’t hear the falsetto caterwauling of power metal in NBM.
And yeah, there’s a lot of bands out there that fit the description to some degree: Dark Tranquility, Dimmu Borgir, Tiamat, Children of Bodom, Entombed, Emperor, Hypocrisy, Satyricon, etc. etc.
In fact, Ihsahn, formerly of Emperor, came out with an amazing album earlier this year that is a kind of Norwegian Free Black Jazz Metal. There’s a review on my blog with link to half the album’s songs, if anyone is interested.
