2021 marks 30 years since the formation of extreme metal pioneers, Emperor.  Formed in 1991, their game-changing debut In The Nightside Eclipse (1995) set the template for symphonic, bombastic, melodic black metal, whilst their follow-up record, Anthems To The Welkin At Dusk (1997) became an instant hit.

Emperor were a force to be reckoned with as underground, experimental and extreme forms of music twisted expectations throughout the end of the 20th Century. 2001 saw the end of Emperor with their fourth album, the ambitious and labyrinthine Prometheus: The Discipline Of Fire & Demise.
