Groump has 1 Mass Worship concert.

Hailing out of Scandinavia, MASS WORSHIP is a darkened metal band tastefully adding onto the rich legacy of Scandinavian metal with their uniquely heavy and gritty sound. The Stockholm-based band was officially formed in January of 2018, but the members carry a rich history comprising of relentless touring and recording schedules and the future that lies ahead of MASS WORSHIP will be no different.
