Faithful to their roots they sing in their native language. They have just released a video for the song
Niðavellir from forthcoming album Vogguvisur Yggdrasils.
The lyric video (yes Icelandic video) is a bit special, because it is filmed as the band here the mix of Niðavellir for the first time - they nod along, singalong and smile. Well worth a gander!
