Californian sludge metal band High on Fire have just announced the release date for their upcoming album, 'De Vermis Mysteriis.' The band's sixth record and follow-up to the critically acclaimed 'Snakes for the Divine,' 'De Vermis Mysteriis' is set to drop on April 3.

'De Vermis Mysteriis' was recorded at the Salem, Mass., GodCity Studios, which is operated by Converge guitarist Kurt Ballou. Produced by Ballou, the 10-song effort is heavily based in literature. The album title translates into 'Mysteries of the Worm,' named after a fictional grimoire novel by 'Psycho' author Robert Bloch. The theme was also incorporated by legendary fantasy author H.P. Lovecraft.

According to the official press release, "The album carries a deeply mystical undercurrent, incorporating fantastical themes and lyrics detailing, among other things, time travel, a serum called liao that is made out of a black lotus and 'a Jesus twin who can see the past through his ancestors' eyes.' And that's just scratching the surface!"

High on Fire frontman Matt Pike offered a short and cryptic teaser for the upcoming release:
