Information: - Nordic folk music includes a number of traditions in Northern European, especially Scandinavian, countries. The Nordic countries are generally taken to include Iceland, Norway, Sweden, Denmark and Finland. The Nordic Council, an international organization, also includes the autonomous territories of Aland, Greenland and the Faroe Islands. Historically, the term "Nordic" was also applied to Baltic countries of Estonia, Latvia and Lithuania. - The Viking Age is the period from late 8th century to mid 11th century in European history, especially Northern European and Scandinavian history, following the Germanic Iron Age. It is the period of history when Scandinavian Norsemen explored Europe by its seas and rivers for trade, raids, colonisation and conquest. In this period, the Norsemen settled in Norse Greenland, Newfoundland, and present-day Faroe Islands, Iceland, Norway, Scotland, England, Ireland, the Netherlands, Germany, Ukraine, Russia, and Turkey. Though Viking travellers and colonists were seen at many points in history as brutal raiders, many historical documents suggest that their invasion of other countries was retaliation in response to the encroachment upon tribal lands by Christian missionaries, and perhaps by the Saxon Wars prosecuted by Charlemagne and his kin to the south, or, were motivated by overpopulation, trade inequities, and the lack of viable farmland in their homeland. Information about the Viking Age is drawn largely from what was written about the Vikings by their enemies, and primary sources of archaeology, supplied with secondary sources like the Icelandic Sagas. - Heavy metal (or simply metal) is a genre of rock music that developed in the late 1960s and early 1970s, largely in the United Kingdom and the United States. With roots in blues rock and psychedelic/acid rock, the bands that created heavy metal developed a thick, massive sound, characterized by highly amplified distortion, extended guitar solos, emphatic beats, and overall loudness. Heavy metal lyrics and performance styles are sometimes associated with aggression and machismo. - Tomas '' Ace '' Borje Forsberg , known by the stage name Quorthon ( 17 February 1966 -- c. 7 June 2004 ) , was a Swedish musician .

Viking metal is quite diverse as a musical style, to the point where some consider it more a cross-genre term than a genre, but it is typically seen as black metal with influences from Nordic folk music. Common traits include a slow-paced and heavy riffing style, anthemic choruses, use of both sung and harsh vocals, a reliance on folk instrumentation, and often the use of keyboards for atmospheric effect.
