Demoncy

Demoncy is a seminal American black metal band formed in 1989 by ex-Profanatica guitarist Ixithra. They are known for their sparse arrangements and ominous atmospheric chord progressions with emphasis on the interplay of rigidly structured harmonies against dissonant execution. Song lyrics are intentionally vague with interpretation left to the listener, but undeniably centered on occult and magical themes. Not limiting themselves only to Satanism or similarly popular paganist thinking, the band are fiercely anti-collectivist.
