Grima plunged Hellfest into an icy torpor, draping festivalgoers in their atmospheric black metal. A performance carried by the dark melodies of the album Nightside, released in 2025. Grima's music is as cold and fatal as the land where it was born: Siberia. Formed in 2014 around twin brothers Morbium and Vilhelm Sysoev, the band has since crafted a unique universe, fueled by pagan imagery and sounds that are both brutal and hypnotic. Filmed on June 21, 2025, at the Hellfest Open Air Festival, Clisson.
