Although Blasphemy’s recorded output was limited, its endurance over the last three decades is a testament to its originality and extremity, and it all began with the Blood Upon the Altar demo. Blasphemy entered Fiasco Bros. studio in 1989 with an $800 budget. They emerged having produced one of the most devastating demo recordings ever made. Blood Upon the Altar ushered in a new style of Black Metal, no less dark or evil than their contemporaries, but more confrontational, more violent. In addition to being heavily inspired by Bathory, Sodom, and Slayer, Blasphemy also drew from the punk infused Brazilian scene, especially Sarcófago, as well as Grindcore bands like Blood and Genocide (Repulsion). The resultant mixture of these influences yielded a demo that established a new standard for extremity in Black Metal, a bar that Blasphemy would continue to raise with each subsequent recording. This is the Die Hard edition on red vinyl. Essential.
