Behemoth played their In Absentia Dei livestream earlier this year from the inside of a Polish church, and has just released it as a live album called In Absentia Dei. You can check out their performance of "Slaves Shall Serve" above.
"In Absentia Dei was a massive challenge and a huge risk, but it was a great artistic and commercial success," said vocalist and guitarist Adam "Nergal" Darski. "The response was absolutely brilliant – we made a statement with this performance and set the bar high. I hope that we can continue to raise the bar with the projects to come!"
