Dark Heresy was a death metal band based in suburban London, England and mainly active during the years 1993-1996, a period during which the London underground metal scene peaked. They played over fifty concerts across England during this period, often as headliners (including one night headlining the Marquee) as well as supporting bands like Ancient Rites, Cradle of Filth and Dissection. They split up in 1997 following some line-up difficulties.
