High on Fire's 'De Vermis Mysteriis' is a brilliant work both musically and conceptually. The album tells the story of Liao, the twin of Jesus Christ, who died so his brother could live. Liao immediately becomes a posthumous time traveller and creates a serum to see the past through the eyes of his ancestors in a quest to understand how his twin became a religious icon. If you're not sold already, the band's pummeling work as a trio and the captivating Lemmy-like voice of Matt Pike will have you playing 'De Vermis Mysteriis' on heavy rotation.
