Nordic folk legend Eivr will return to the Josef fortress after an eight-year absence, bringing a sense of Nordic atmosphere inspired by the Wardruna project from the Faroe Islands. The festival will also welcome American thrash metal band KYLESA following their extended hiatus. Honoring the genre, Sacred Reich will be part of the lineup ensuring a solid representation of honest thrash metal. In addition to these new additions, Blackbraid, Illdisposed, and Psygnaut will join the festival, expanding the musical diversity for 2026.
