THIS GIFT IS A CURSE formed in Stockholm, Sweden in 2008, founded by vocalist Jonas A. Holmberg and drummer Johan Nordlund, with their debut EP recorded at the legendary Sunlight Studios with producer Tomas Skogsberg in 2010. The band works in a cataclysmic fusion of black metal, sludge, and hardcore, constructing songs that balance ferocity with a suffocating, doom-laden atmosphere. Full-lengths I, Guilt Bearer (2012), All Hail the Swinelord (2015), A Throne of Ash (2019), and Heir (2025, released on Season of Mist) have steadily built their standing in the European extreme underground.
