nattens madrigal is genius!! Do you know the book "Lords of Chaos"? There is a good interview with Ulver talking about wolf & werewolves. :-)
Ulver also made a soundtrack for a norwegian werewolf movie:

As you mentioned there are a lot of Black Metal songs about werewolfs:

Temnozor - Werwolf (very good black metal band from Ukraine with folk influences)
Satanic Warmaster - The Burning Eyes of the Werewolf (sounds very underground)
Gehenna - Werewolf (Gehenna is cool, athmospheric midtempo black metal)
Satans Elite Kommando - Werwolf, Dämon der Nacht (stupid name, stupid music, but somehow funny ;-))
Beherit - Werewolf, Semen and Blood (Beherit is underground & sick. eerie, dark & very evil)
...

Kveldsanger is a good neofolk album. If you like this cd, you should check out Empyrium (with Schwadorf from the vision bleak) with their album "Where at night the wood grouse plays" from germany.

they have also some more powerfull songs:

If you like Empyrium & Black Metal you should listen to "Sun of the sleepless". It is also a project of Schwadorf....

They have made my favourite Black Metal Song "Tausend Kalte Winter"...you can listen & downloads the songs on the myspace site.
The band name "sun of the sleepless" is from a Byron poem about the moon:

Sun of the Sleepless! melancholy star!
Whose tearful beam glows tremulously far,
That show’st the darkness thou canst not dispel,
How like art thou to Joy remembered well!
So gleams the past, the light of other days,
Which shines but warms not with its powerless rays:
A night-beam Sorrow watcheth to behold,
Distinct, but distant – clear – but, oh, how cold!

Here's probably a good an introduction as any. The documentary is a failure in terms of an interview, but the scenery is fantastic, and it provides a little bit of insight on one of the better Black Metal bands.

True Norwegian Black Metal

It's segment one of five segments, which you should be able to find the others on the playlist.

Other than that, I like this band, and also a band called Destroyer666, and a few others.

I was wondering if you heard about Moonspell. There's a song about wolves : Moonspell :Wolfshade (a Werewolf Masquerade)
"She brought the Night hidden in her sad Wolf eyes
The perfume of a twilight, her strongest scent
Half Wolf, Half female - what a strange wedding
Mother Nature has offered us to see..."

Metallica does not suit this topic, they are not a black metal band. You do not get/post the songs on this site. If you want to talk about wolves, move over to another forum area and please don't revive ancient threads.
