Ah, finally I have it in my player: "Urkraft", the third album of Sweden's Viking Metalians THYRFING.
"Mjölner", just like the name implies, starts out with a hammer ringing on an anvil, then the typical THYRFING-sound sets in. But halt! Not so typical, in fact, because somehow they DO sound different... The keyboards are not as thickly layered anymore and, hey, what is that? A clean voice accentuates Thomas Väänänen's usually rough vocals, sounds different, but good, very good in fact! They also are putting more emphasis on clearer song-structures, benefiting their sound very nicely as well.
"Sweoland Conqueror" impresses by its majestic riff, "Home Again" with its wide variety and the intelligently implemented acoustic guitar, while "The Slumber Of Yesteryears" has a simple rhythm with a folky, almost polka-like melody, before flows into a mid-tempo Viking Metal-track, just to return to the melody, borne by the keyboards.
"Till Valfader Gamle" then is pure Viking Metal again, sometimes a little more moderate, then again in its full excellence, while the following title-track is a gemstone by itself, showcasing all the ingredients and assets of the THYRFING-sound.
The icing on the cake is the awesome cover-version of the Gary Moore-classic "Over The Hills And Far Away", completely sung with the clean voice, with a thundering rhythm and just an ideal interpretation overall.
So, THYRFING still sound like THYRFING, just different, got it? The keyboards are used more effectively and the songs have far more structure than before. But you can twist and turn as you want to, "Urkraft" is majestic Viking Metal at its best.
