Track 1 from Obliteration's 2007 album, entitled "Perpetual Decay." These guys are from Kolbotn, Norway (Darkthrone, Nekromantheon, etc.) Their two guitarists are also members of Nekromantheon. If you're not familiar, do yourself a favor and check them out, as well.
I own no rights to Obliteration's music or album art- I am simply sharing their music, since I could find none from this album, on YouTube.
