Power metal is all about rousing battle anthems featuring soaring vocals, symphonic drama and speedy rhythms. “Holy Diver” showcases Dio's operatic pipes and fantastical poetry. Helloween are equally vital, with cuts like “Wake Up the Mountain” offering a clinic in epic composing and neoclassical guitar runs. On “The Siren”, Nightwish infuse the style with dreamy, new age-inspired lushness.
