Antlers, human and animal bones. There are a lot of nature-made clothes and instruments on that stage.

Krig means war in ancient and modern nordic languages. Galdr means incantation. So krigsgaldr means War incantation. Preparation for war. This song was constructed from reading ancient texts and coins from when the Vikings fought the roman armies on the east shores of modern day Britain.

Good reaction vid.
Yes, self made instruments & clothes, & yes, Maria is tapping human forearm bones.
The music vid that accompanies this song, gives u an idea what they are singing about.
Heilung are Pagan.  
Hope to see u check out more Heilung.

I'm always a bit disappointed when this is the very first Heilung song that people discover and listen to.  It's the only one with English lyrics.
