A cohesive concept album about the struggle to conquer Valhalla with swords and honor, Surtur Rising is also a take-no-prisoners sonic explosion. The mighty guitars of "War of the Gods," punishing death-march "Destroyers of the Universe," emotional wreckage of "The Last Stand of Frej," and doomsaying chant of "Wrath of the Norseman" are Amon Amarth in their purest form. From start to finish, some of their most memorable riffs and tunes shore up these mythological images of wartime valor.
