Faun is an interesting European folk band. The membership is a bit fluid, but they are always good.
This is “Rosmarin” from their 2005 album Renaissance.
The group Faun is a bit tough to categorize outside of “folk.” They have been called “dark folk,” but that is mostly in the European music press. On this side of the Atlantic they are usually styled “pagan folk.” (I just like the music, and the fact that you don’t get hear things like a hurdy-gurdy all that often.
