Oathean is a South Korean black metal band that formed in 1993 originally under the name 'Odin', for the Norse/Scandinavian god. They went on a short hiatus and then changed their name three years later. Oathean's lyrics tend to deal with themes of sadness and depression. Their particular style of metal is influenced by folk metal, and incorporates Korean world music with the use of traditional Korean instruments such as the haegeum and daegeum.
Founding member Do-Su Kim started and runs his own label, Jusin Productions, which releases much of the band's output, and has joined in for sessions with Holymarsh.
