Nightwish is a symphonic metal band from Kitee, Finland. The band was formed in 1996 by lead songwriter and keyboardist Tuomas Holopainen, guitarist Emppu Vuorinen, and vocalist Tarja Turunen, who was replaced in 2007 by former Alyson Avenue singer Anette Olzon. In 2002, original bassist Sami Vänskä was replaced by Marco Hietala, who also took over the male vocalist role previously filled by Holopainen or guest singers.
Although Nightwish has been prominent in their home country since the release of their debut album, Angels Fall First (1997), they did not achieve worldwide fame until the release of the albums Oceanborn (1998), Wishmaster (2000) and Century Child (2002). Their 2004 album, Once, has sold more than 1 million copies and was the band's breakthrough in the United States. Their biggest US hit single, “Wish I Had an Angel” (2004), received MTV airplay and was included on three US film soundtracks to promote their North American tour. The band produced three more singles and two music videos for Once, as well as a re-recording of “Sleeping Sun” for the “best of” compilation album, Highest Hopes (2005), before Turunen's dismissal in October 2005.
In May 2007, Nightwish announced Olzon as Turunen's replacement. That September, the band released their sixth album, Dark Passion Play, which has sold almost 2 million copies. The album's lead single, "Amaranth", became one of Nightwish's most successful in Europe. The supporting tour, one of the band's largest, started on October 6, 2007 and ended on September 19, 2009. The band released an E.P./live album, Made in Hong Kong (And in Various Other Places), in March 2009 as a MCD/DVD, and their seventh studio album, Imaginaerum, was released globally on various days in late 2011/early 2012.
On October 1, 2012, Nightwish announced that they had parted ways with Olzon and will be finishing the current tour with ReVamp vocalist Floor Jansen.
Nightwish is the third-best-selling band and musical entity in Finland with sales of more than 900,000 certified copies. The group is also the most successful Finnish band worldwide, selling more than 8 million records and receiving more than 60 gold and platinum awards
