Terve,
No I didn't know Garmarna, but they sound good. Some fifteen years ago I was actively following Finnish / Swedish / Carelian folk-inspired music scene, but I'm afraid I'm not up to date any more =)

As an anecdote from those years; it was Kaustinen Folk Music Festival, probably 1997 or so, there were a lot of memorable bands playing, like Gjallarhorn and Wimme Saari. Then there was an award-winning group called Loituma, and I found one of their songs very catchy, for years the song stuck like an earworm and I was humming or whistling the melody to myself. Later on I learned that I'm not the only one who has found that particular tune being somewhat catchy...
