The offering will be released on January 30th via Immortal Frost Productions, coming in various physical formats, as well as on digital format through all major platforms.

In the album, you can hear the guest vocals by Tubal-Qayin of Völniir on the song “Rotborn Terror”, while all lyrics were written by Isfeth.

Sidious is a UK-based black metal band that evolved from their early blackened death metal style, formed in London in 2012. They are known for their themes of nihilism and blasphemy and have released albums like “Revealed in Profane Splendour” and “Blackest Insurrection”. Sidious offer a magnificent, majestic outpouring of pure, unadulterated black metal that places the band in the vanguard of Albion’s legions. Having honed a ferocious reputation in the UK underground scene, they have adultered a  unique brand of bleak extremity that will, once again,  fall  upon the earth.
