Acheron (/ˈækərən, -ɒn/) was an American death/black metal band from Pittsburgh, Pennsylvania that was formed by Vincent Crowley in 1988. The band is named after the mythological river Acheron (Ancient Greek: Ἀχέρων – Akhérōn) located in the underground kingdom of Hades in ancient Greek mythology. They are not to be confused with 1990s Australian death metal band Acheron, nor the 1980s/1990s American power metal band Acheron, nor any of several lesser known European thrash and death metal bands also known as Acheron between the 1980s and the present.
