Watch on SFlix. At the end of 2021, Powerwolf - the most successful German metal band to date - fascinated with a streaming event of unprecedented dimensions. Those who thought they had seen everything in the live sector were instantly proven wrong with unmatched audio production and visuals that can only be described as simply breathtaking. The concept of The Monumental Mass - A Cinematic Metal Event was conjured by Powerwolf mastermind Matthew Greywolf, who is also involved in the screenplay, while Jörg Michael is responsible for the cinematic production. The artwork was once again created by Zsofia Dankova, with audio production, mixing and mastering by Kristian Kohle Bonifer.
