It is a Russian band who sing in Finnish, though they don't speak the language. Sounds weird but it works. The music is atmospheric, a bit ambient combined with some heavier feel. Somewhat like the Icelandic band Solstafir. This latest album has lyrics written by a friend of mine who has written many albums over the years herself as a solo artist, a woman called Marja Mattlar.
