I couldn’t find much information about this musician or the song itself. Only a You Tube video followed by a stream of bizarre comments. If any informed viewers have any more knowledge about the song though – or the musician – I would be very interested.
Man may be mortal, but a good song can last through the centuries. It’s good to hear these viking ballads are alive and well, being sung the same online as they were many a century ago on a cold winter night amid Norse folk keeping warm with good mead and company.
EDIT: According to a helpful commenter below, the first song here relates to the great Heathen Invasion of 1066 and the battle at Stanford Bridge.
The band is called Harold Foss and the following is their home page: http://www.legende.no/
