Gruff billygoat's 'Religiøse Folketoner'

Another guy to find out more about: Arve Moen Bergset, singer, member of the group Bukkene Bruse, hardanger fiddle player and classical musician. I heard him singing a song called "Min sjael nu lover herren" on NRK and looked him up on the web. He has a marvelous tenor voice, lots of ornamentation on the song. Sounded a lot like Irish sean nos as James Flannery might sing it.

The Norwegian Music Information Centre has a biography of Bergset. According to Wikipedia, he is a first violinist in the Oslo Philharmonic Orchestra. Two clips from one of his early folk albums have been posted to YouTube: The first one includes:

1- 'Pal Sine honnor': Paul let the hens run over the hillside when the fox was abroad and was afraid to go home to his family's farm.
8. Eg var liten ((When) I was little) Sitting by the open cottage fire on her stool

2- 'Eg er Framand': I am a pilgrim who will stay only one night here. I seek the City of God where sorrow & death are no more. Dear Lord, lead me to Heaven's shore.

The second includes:

'Pa Dovrefjell':Queen Ingeborg's twelve brothers were heroes without equal, who could control the weather & tides, swim like a fish, stand on waves, play a golden harp to which all must dance, blow a horn so that all hearing it feared, capture a dragon . . . This say I and it is true: their like is not found in Norway's land.

'Mit Hjerte Altid Vankor': Xmas carol. My heart always wanders to where Jesus was born, where my longing finds its home.

He began recording when he was 14 years old, and these sound like they were recorded then.

There's also an album on the "This is Music from Norway" website called Religiøse Folketoner. Playlist:

The clip I heard is on this album.

It sounds like he does some interesting classical/folk stuff. According to MIC Norway:

Arve emphasises that he is not a genuine dance fiddler because although he has been playing the Hardanger fiddle since the age of fifteen, it has mainly been in a classical context. He has recently recorded Geirr Tveitt’s Two concertos for the Hardanger fiddle with the Stavanger Symphony Orchestra conducted by Ole Kristian Ruud. On an earlier CD, he played Johan Kvandal’s Fantasia for hardingfele og strykere (Fantasia for Hardanger fiddle and strings) with the Kristiansand Symphony Orchestra.
