Wintersun was originally created by guitarist Jari Mäenpää as a side project to folk metal band Ensiferum, for whom he was lead singer and guitarist. In 2003, Mäenpää began pulling together songs that he had been working on since 1995. These songs followed specific themes described by Mäenpää as majestic, "spacy", and melodic. While Mäenpää planned to perform and record each instrument for the first album himself, he still required a drummer. He sent demos to Kai Hahto, former member of Rotten Sound, who agreed to perform the drums.
After obtaining a record deal, Mäenpää scheduled studio time to record the first album. Ensiferum's tour to support their 2004 release was scheduled at the same time, which forced Mäenpää to request time off from the band. The band instead fired him, and Mäenpää was free to go ahead with the production of his self-titled album, Wintersun.
After the release of Wintersun, the band found permanent members to perform shows and promote the album, although a keyboardist would never be found. In 2006, Wintersun began work on their second and third albums, Time I and Time II, which were initially intended to be released as a single album. Recording began in May of that year, but the albums would be the recipient of years-long delays for a multitude of reasons, not the least of which was the complexity of each song's mix. Time II will be released in early 2014.
2003–2004: Creation and Wintersun 
|“||I have a little bit of a mournful, melancholic, majestic or kinda "spacy" way of writing, when it comes to melodies.||”|

Jari Mäenpää began Wintersun in 2003, "to make songs that make you feel like you are floating in space." Mäenpää chose the name "Wintersun" from a list a friend had produced, later explaining, "Winter reflects the cold and stormy side of the album and also the Finnish melancholy and magic. Sun is related to the 'universe, space and stars'-feel of the album, which is also strongly connected to the lyrics." Although the songs that would appear on Wintersun had collectively been written between 1995 and 2004 (see each track's respective composition dates here), Mäenpää kept his songwriting efforts primarily focused on folk metal band Ensiferum, with whom he'd been playing since 1996.
Mäenpää contacted Rotten Sound drummer Kai Hahto, who, upon hearing demos, agreed to work as the session drummer for Wintersun. Mäenpää and Hahto recorded demo versions of "Winter Madness," "Beyond the Dark Sun," and "Death and the Healing", which were sent directly to Nuclear Blast. The label offered a contract for several albums stipulating that a three-song demo must be approved before each new album is recorded.
Even after obtaining a record deal, Mäenpää intended on keeping Wintersun as a side project during his tenure as lead singer and guitarist for Ensiferum. Unfortunately, to support the 2004 release of Ensiferum's Iron, Spinefarm Records scheduled a European tour with dates that conflicted with studio time Mäenpää had booked to record Wintersun. After requesting a break from the band, Mäenpää was fired from Ensiferum.
Mäenpää focused his energies on recording Wintersun despite the lack of formal band members. The vocals, guitars, bass, and keyboards on Wintersun were performed solely by Mäenpää, who was already adept at recording multi-instrumental songs, having grown up with 8- and 16-track equipment. Three studios were used in the making of Wintersun: drums were recorded at Tico-Tico Studios, Mäenpää's vocals, synth, and guitarwork were recorded at Sundi Coop Studios, and Nino Laurenne mixed the album at Sonic Pump Studios. Mäenpää recorded additional synth and guitar solos on his 16-track recorder.
Wintersun was released on 13 September 2004. Although Mäenpää enjoys writing his music without limiting it to any genre, the myriad styles in Wintersun have been broadly described as power metal, folk metal, melodic death metal, neo-classical metal, black metal, and Viking metal.
2004–2006: Band formation and Wintersun promotion 
Inspired by Wintersun's musical direction, Kai Hahto left Rotten Sound and joined Wintersun as permanent drummer, and Jukka Koskinen, of Norther, would join Wintersun as bassist. Oliver Fokin, former drummer for Ensiferum and whom Mäenpää credits as inspiring him to start playing guitar, was hired as guitarist. The search for a keyboardist proved to be ineffectual.
On 4 October 2004, Wintersun announced the departure of Oliver Fokin as guitarist, and a suitable replacement would not be found until 27 December, when Teemu Mäntysaari joined. The search for a keyboardist continued, and Wintersun was forced to use backup tapes for their future performances.
2006–2014: Time I and Time II 
Recording for the second album, tentatively titled Time, began on 2 May 2006. Wintersun entered Sonic Pump Studios with Thunderstone's Nino Laurenne as sound engineer. Recording of Hahto's drum tracks began on 3 May. Rhythm guitars and bass were also recorded during the session. Mäenpää would record synthesizers and sampling, guitar solos, acoustic guitars, vocals, and Mäntysaari's guitarwork at his apartment studio. The album will have seven songs and an intro and outro. The songs' compositions are complex, being composed of 200 to 300 tracks each.
Time would face multiple setbacks, delaying the album's release for years. On 23 October 2006, Wintersun released a statement that, because recording was continually delayed, the dates for the album's mix would be pushed back to May 2007, causing Wintersun's appearance at Ragnarök Festival that same month to be cancelled. A tentative release date for August 2007 was given.
On 17 April 2007, Mäenpää released a statement updating the status on the album, detailing that difficulties with hardware failures caused further delays in the recording process. The mix dates were cancelled, and because Laurenne's schedule at Sonic Pump Studios was full for the remainder of the year, the album's release would be pushed back further. By this time, all guitars, including solos and acoustic, were recorded, and the intro was completed. Mäenpää had begun composing and arranging the synth layers, but stress and frustration had been hindering his creativity.
Hahto issued an update on 5 June 2008, explaining that the album's delay would be indefinite. Difficulties with computer hardware were due to the limited amount of RAM affecting Mäenpää's ability to compose orchestrations in real time. The band appeared in Metalcamp in July 2008.
While technical difficulties pursued Wintersun into 2009, problems impeding the album's progress would eventually include Mäenpää's actual apartment.[A] The increase in stress caused Mäenpää to have writer's block. Wintersun cancelled all 2009 promotional tours to focus solely on the album's completion.
On 17 November 2010 the Wintersun Official homepage was updated stating that they would again be playing live shows. Three events, Metalfest, Bloodstock and Metalcamp were announced. The reason stated for these shows was a deal with their label, providing money for new computer hardware in return for playing these shows.
On 16 March 2012, Wintersun announced via their official homepage that they will headline the Heidenfest Tour in October 2012. The band also stated that the mixing of their new album, Time, is going well and that a release is planned for late summer of the same year; they also stated that Time will be split in two albums.
On 18 July 2012, Wintersun announced on their official homepage that part I of "Time" will be released on 12 October 2012.
Time I was released on 19 October 2012.
Mixing for Time II began in early 2013. The band stated the "album will continue where 'Time I' left [off]" and will include seven guitar solos. The album is expected to be released in early 2014.
