"De Mysteriis Dom Sathanas" is the first full-length studio album by the Norwegian black metal band MAYHEM. Songwriting began in 1987, but due to the suicide of vocalist Per "Dead" Ohlin and the murder of guitarist Øystein "Euronymous" Aarseth, the album's release was delayed until May 1994. "De Mysteriis Dom Sathanas" is widely considered one of the most influential black metal albums of all time. Limited to 1000 copies!
