barathrum

n. (Latin) hell, abyss, hades; unsatisfiable glutton, person who eats to excess

Barathrum meaning 'an insatiable person' or 'an Abyss'. More recently associated with a Finnish black metal band. They were one of the first Finnish black metal bands together with bands such as Archgoat, Beherit and Impaled Nazarene. They originate from Kuopio but have since re-located to Helsinki. The first letters of their full-length albums spell "HEIL SOVA" (referring to the band's mainman, Demonos Sova), which completes their original eight-album plan and they are only touring now.
