Imagine for a second if Ensiferum was a warrior woman and Finntroll was a warrior...troll. They made sweet passionate love in the forest (real nice thing to imagine). The resulting offspring would be Equilibrium, who would go on to make himself a living legend.
And why not? When I think of Equilibrium's Sagas, I think of a combination of Finntroll and Ensiferum's sounds to make one epic folk metal album. You have the fast paced guitar tremolos and drums like Ensiferum, and overblown folk instruments and fanfare like Finntroll. You've got the best of both worlds here!
Equilibrium only sings in German, but the real thing to pay attention to is the music. "Prolog auf Erden" is an awesome way to get things rolling. It's one of those intro tracks that starts out the album with actual music instead of just ambiance or spoken prologue. Among other highlights is one standout song titled "Unbesiegt", which sounds like a battle in a rain forest with the South American-esque flutes making it a very unique and interesting song by a European folk metal band.
Everything climaxes at the epic 16 minute instrumental at the closing of the album, "Mana". Besides some choral "oooh"s and "aaah"s, the music is the only thing telling the story here. This song is a folk metal opus. It'll make you feel like you and your battle party are ascending some heavily occupied enemy citadel, fighting really tough enemies, fighting mini-bosses, finally reaching the final boss, killing him/her/it, and flying your team's banner on the top of the compound as peace returns to the land. ...wow that sounded really nerdy. :/
This is my favorite folk metal album right now. If you can get past the huge length of this album (79 minutes, a quarter of which is taken up by "Mana"), you'll find this really awesome too.
