The organizers of the Berlin-based festival De Mortem Et Diabolum have confirmed that Panzerfaust and Sumerian Tombs will join the lineup for the event’s December 2026 edition. Held annually, the festival has established a reputation for focusing on the darker and more experimental facets of the black metal genre. Canadian outfit Panzerfaust is recognized for their complex, philosophical approach to extreme music, while Germany’s Sumerian Tombs provides a more traditional but highly atmospheric aesthetic. These additions further bolster a roster that historically features some of the most innovative acts in the underground scene. The festival takes place over two days and serves as a significant year-end gathering for practitioners and followers of extreme metal. Tickets for the event are currently available through the festival’s official online store. Further lineup announcements and specific stage times are expected as the event approaches the winter season.
