MAYHEM have officially announced a series of events celebrating the 30th anniversary of their 1994 debut full-length "De Mysteriis Dom Sathanas" — widely considered the foundational text of the Norwegian black metal tradition and one of the most historically significant albums in extreme metal history. The anniversary celebrations, announced for the second half of 2026, will include a remastered reissue of the album, a limited special edition box set, a documentary film, and a series of concert performances at select European and North American venues.
The album, whose recording and release were inseparable from the most notorious chapter in metal history — Dead's suicide in 1991, Euronymous's murder by Varg Vikernes in 1993, the Norwegian church burnings, and the widespread media hysteria of the early 1990s — remains a genuinely divisive artifact: musically extraordinary and historically important, but forever entangled with violence and tragedy that cannot be separated from its creation. MAYHEM's current vocalist Attila Csihar, who performed on the original recording, will participate in the anniversary events, as will guitarist Necrobutcher and drummer Hellhammer.
The remastered edition of "De Mysteriis Dom Sathanas" was completed at Strype Audio in Oslo by engineer Tom Kvålsvoll, who worked extensively to restore the album's original analog warmth while preserving the raw production aesthetic that Euronymous achieved at Grieghallen Studio. The anniversary box set will include the remaster, a replica of the original typewritten lyrics sheet, photographic prints from the 1992-1994 period, and a detailed essay on the album's creation by Norwegian music historian Gunnar Sønsteby. A release date of May 25, 2026 has been confirmed — the exact anniversary of the album's original 1994 release date.
