"Nibelung" is the last worthy chapter of Siegried's trilogy. The Austrian formation has perfectly forged their unique steel hymns and epic metal sounds characterized once again by heavy guitar riffs, powerful choirs, and sonourous keyboard melody lines. The song material is crowned by the interaction of the three vocalist, whose voices bring various Nibelung Saga characters to life. At the helm is none other than the extraordinary Sandra Schleret (Elis, ex Dreams of Sanity), whose singing talents provide the final touch to the refrains and melodic arches. The epic sound is the work of Alex Krull's Mastersound Studo (Elis, Leaves' Eyes). "Nibelung" is an album with which Siegfried should attain legendary heights.
