Alright, so here is a thread just for heathen music and any impact it has/had on us or our practices, if any. Or if its just for the sake of jamming out. I'll start.
Amon Amarth - Amon Amarth has a special place in my heart. Their music led me to becoming a heathen. their song 'Asator' got me reading about Thor, and later, the myths. and 'Runes to My Memory' got me studying the runes, which have been my passion since i started a few years ago. They also have a few good songs about the myths soch as 'Tock's Taunt - Loke's Treachery" and has some decent, relatively accurate songs about the Gods (in this case, when i say gods, i dont mean exclusively the gods. im also referencing the Jotnar, Muspel, Alfar, etc etc.) such as 'Destroyer of the Universe' which is about Surt. Also, with them you can just jam out to the deeds of your ancestors, with songs such as 'An Ancient Sign of Coming Storm' or 'Cry of the Blackbirds' or, throw on your war face and blare 'Valhall Awaits Me.'
Tyr - Tyr is just great. 'Hold the heathen hammer high' made me proudly and openly heathen, and gave me less of a "this is wierd" feeling about it, which i had before then. They also have songs which are about the Gods and myths, such as 'the Lay of Thrym' which, obviously is about the lay of Thrym (sort of), or 'Lord of Lies' which is about Loki.
Rebellion - Rebellion has songs referencing the sagas, the Gods (again, i use this term loosely), with references to the Einherjar, Ragnarok, and some famous/awesome heathens such Harald Hadrada, Erik the Red, and some not-so-great people, like Olaf Trygvasson. their song 'Loki' also beautifully states that Loki isnt entirely evil, and has done alot of good. I would highly recommend their 'Arise' album.
Some personal favorites simply due to lyrical content and relevancy:
Fenrir: Raising Fear
"And when the wolf comes
One voice breaks the night
Asgardh unite! Asgardh unite!
All of the godsre coming
Heading the call
Asgardh unite! Asgardh unite!"
Rancid: Loki
"Is he good today, or is he evil?..
Loki's playing tricks again,
Loki's playing tricks again".
Rebellion: Loki
"What would Odin be
Without Gunghir I gave
And to Thor I presented
Mjlnir as a fave
What would Asgard be
Without the wall I had you build
And Sleipnir born of my guilt"
I simply have to add Krauka to your list.
Krauka is a danish/icelandic folk band who plays what might come close to Viking age music. Their instruments are close copies of archeological findings, but they play with their own tune. Over the years they've played at Asatru weddings, rituals and fairs and they are one of my personal favourite bands.
Oh! I love Týr! sinklars visa is probably my favorite.
Also Váli is superb if I was to quiet it down and just relax.
Váli is a dronedoom band from Essex, with large musical influences from Thor's Hammer, Katatonia, Amon Amarth and more.
