Genre: Rock
Acheron is an American blackened death metal band, originally based in Ohio.
Founded in 1988 by vocalist/bassist/songwriter Vincent Crowley (formerly of Nocturnus, and leader of the satanic youth group "Order of the Evil Eye"), Acheron's musical output is almost exclusively Satanic and anti-Christian in content. Early albums featured interludes by Peter H. Gilmore. Crowley was appointed a priest in the Church of Satan by its founder, Anton Szandor LaVey, and began spending a lot of his time debating local televangelists, limiting Acheron's output for a time. He later disassociated himself from the church to act independently.
