Bathory was formed in Stockholm in 1983. Founder Quorthon, a seventeen-year-old guitarist, was joined by bassist Hanoi and drummer Vans. After various name changes (beginning with Nosferatu, then Natas, Mephisto, Elizabeth Bathory and Countess Bathory) they finally settled on Bathory. Their first recording deal came that same year, when Quorthon managed to secure the consent of Tyfon Grammofon's boss to record two tracks for the compilation Scandinavian Metal Attack. The tracks which he recorded gained unexpected attention by fans. Soon afterward, Tyfon Grammofon contacted Quorthon and asked him to record a full-length album.Although Venom's Black Metal, released in 1982, was the first record to coin the term, it was Bathory's early albums, featuring Satanic lyrics, low-fi production and an inhuman vocal style, that defined the genre. Many fans have speculated Venom was an influence on Bathory; however, Quorthon has said in an interview with Kick Ass magazine in 1985 he only heard of Venom after the first, self-titled Bathory album was released. He also expressed dislike for many influential and popular heavy metal bands at the time, such as Iron Maiden and Judas Priest. He has also stated the band's early work was influenced primarily by Black Sabbath, Motorhead, and punk rock.Bathory's self-titled debut album, and the subsequent releases The Return and Under the Sign of the Black Mark are now regarded as major influences on the Norwegian bands which extended black metal's musical progression and popularity in the beginning of the 1990s.The first signs of what was to follow appeared on what many fans consider to be Bathory's best album, Blood Fire Death, on which some of the tracks the pace had slowed down to allow for a more epic songwriting approach, said to be an influence on, or initiation of, the extreme metal sub-genre viking metal. The Viking theme was also first introduced on this album. However, most of the musical elements of black metal were still present.With the release of Hammerheart Bathory had changed style towards less aggressive, more epic and atmospheric music; the lyrics dealt with themes about Vikings and Norse mythology. Partially influenced by the American power metal band Manowar, Hammerheart was a landmark album that "formally introduced" to the metal world the "archetypical Viking metal album." The style of Hammerheart was further demonstrated on the subsequent Twilight of the Gods and Blood on Ice (the latter of which was mostly recorded before Hammerheart in 1989, but not finished or released until 1996 because Quorthon thought it would be too radical a departure from his previous work for fans to process).With Requiem, released in 1994, Bathory changed style once more, this time turning to retro-thrash in the vein of 1980s Bay Area thrash bands. In recent years, many critics have seen Bathory's output as increasingly erratic, as the band returned again to Viking themes and, with the Nordland albums of 2002 and 2003, largely abandoned the retro-thrash sound of the mid-1990s in favour of the more popular, more epic style for which they are best known.In June 2004, Quorthon was found dead in his home, apparently due to heart failure. He was known to suffer from heart problems in the past. On June 3, 2006, Black Mark Records released a box set in tribute to Quorthon containing three CDs of his favorite Bathory and Quorthon songs, a 176 page booklet, a DVD with his long-form video for "One Rode to Asa Bay", an interview and some rare promo footage, and a poster.
