Neo-folk! I love it. Ian Read (Current 93/Sol Invictus) formed Fire + Ice to express his views on "…magic lore, runes, tradition, renaissance medievalism, Nordic mysticism and other esoteric and occult mysteries." Phew. That'll work. It's typical of the genre, with slow acoustic moments and traditional skin drums played in a very harmonious, ancient, pagan way. Part of the album is a runic poem; the lyrics are multi-faceted and will take knowledge of Runes and an age to decipher.
If hippies and pagans give you the fear, then you should probably avoid Rûna. But if you like the genre, then it's certainly worth seeking out.
