Tarja Soile Susanna Turunen-Cabuli (born 17 August 1977), known professionally as Tarja Turunen or simply Tarja, is a Finnish heavy metal singer, best known as the former lead vocalist of Nightwish. She is a soprano with a three and a half octave range. Turunen studied singing at Sibelius Academy and Hochschule für Musik Karlsruhe. She is a professional classical lied singer, and the former lead vocalist of the Finnish symphonic metal band Nightwish, which she founded with Tuomas Holopainen and Emppu Vuorinen in 1996. Their combination of hard and fast guitar riffs with Turunen's dramatic, "operatic" lead vocals quickly achieved critical and commercial popularity. Their symphonic metal style, soon dubbed "opera metal", inspired many other metal bands and performers. Turunen was fired from the band on 21 October 2005 (just after the performance of the band's End of an Era concert) for personal reasons accompanied by an open letter from the band. She started her solo career in 2006 with the release of a Christmas album called Henkäys ikuisuudesta. In 2007, Turunen released My Winter Storm, an album featuring various styles including symphonic metal, and started the Storm World Tour. She performed several concerts in Europe, playing in metal festivals including the Graspop Metal Meeting and the Wacken Open Air, before releasing her third album, What Lies Beneath, supported by a tour, which lasted until April 2012. Her first live DVD Act I was filmed during this tour on 30 and 31 March 2012 in Rosario, Argentina. Act I was released in August 2012. Turunen started the Colours in the Dark World Tour in October 2013 to promote her new album Colours in the Dark. Her second live DVD was filmed during the events of Beauty and the Beat and was released in May. In September 2015, Tarja Turunen released her first classical studio album, Ave Maria – En Plein Air. In August 2016 she released The Shadow Self with a prequel EP The Brightest Void released on 3 June. Her latest album, In the Raw, was released on 30 August 2019.
