The YouTube clip has a pretty good translation of the title:
Setesdal, Garden of Ancient Songs, Kirsten Bråten Berg/Arendal Big Band. Uploaded by egilso on Oct 12, 2010. KBB performs with ABB in Arendal Kulturhus 14.08.10. Vocals: Kirsten Bråten Berg. Director and arranger: Fred Sturm.
Arendal Big Band's website (in Norwegian) at http://www.arendalbigband.no/. According to Wikipedia, Arendal is a city of 41,000 on the south coast of Norway. A lot of immigrants on East Coast came from Arendal, "as a great deal of Norwegian sailors, trimmers, shipbuilders and carpenters from Arendal settled in areas of New York such as Brooklyn, the Staten Island neighborhood of Port Richmond, and several industrial centers in Northern New Jersey such as Jersey City, Bayonne, Perth Amboy and Elizabeth." Kirsten Bråten Berg was born in Arendal. She now lives in Stetesdal, an inland area to the northwest.
LATER (July 19, 2015). While I was doing something else, I came across an audio file on YouTube at:
https://www.youtube.com/watch?v=iNQhDbtuKdg of the original CD track, apparently copied from a later compilation called Nordisk Sang (Nordic Song), which is where I first heard it. "Min Kverdarlund" by Ale Møller, Hallvard T. Bjørgum, Kirsten Bråten Berg & Tellef Kvifte. Haunting piece of music.
