Marco Hietala

Marco Hietala was born in Tervo, and is the youngest child of the Hietala family. Hietala lived in Tervo until the age of 15, after which he moved to Kuopio to study classical guitar, vocals and musical theory in high school. In 1984, he and his brother, Zachary Hietala, formed heavy metal band Tarot under the name Purgatory. In 1986, Tarot received a deal for their first album and went on tour. Before becoming a full-time musician, he worked as a live and studio sound engineer.

Hietala joined Nightwish in 2001 when Tuomas Holopainen and the band's manager called him and said that there would be a place in the band for a vocalist and a bass player. Century Child was his first Nightwish album, following the departure of previous bassist Sami Vänskä. He was a prominent guest musician in Delain, a project involving many members of the gothic and symphonic metal community. He also participated in the recording of Invitation, by Altaria, providing backing vocals. Hietala has also been part of the bands Sinergy and Northern Kings.

During Nightwish's shows, Turunen would take a break halfway through the set. Before Hietala joined the band, the band would perform an instrumental song during this time. After Hietala joined the band, they performed covers of well-known songs, with Hietala singing the lead vocal part in this break. The band has performed Ozzy Osbourne's "Crazy Train", W.A.S.P.'s "Wild Child", Dio's "Don't Talk to Strangers", Megadeth's "Symphony of Destruction" and Pink Floyd's "High Hopes". Some of these songs have been put up for sale as well on various Nightwish album releases. Following Turunen's departure from Nightwish, Hietala was much more involved with the production of Dark Passion Play, which was released in September 2007. He sang some songs, completely, and wrote the music for the song "The Islander", on which he also plays acoustic guitar instead of bass. Hietala is also credited alongside Holopainen for co-writing the song "The Crow, the Owl and the Dove" from Nightwish's 2011 album, Imaginaerum.

In March 2009, Hietala joined the band Sapattivuosi. They cover Black Sabbath songs in Finnish. In this band, however, Hietala does not play bass; he only performs vocals.

On 1 April 2010 it was said that Hietala would leave the band to concentrate on a choir career. This was identified as an April Fool's joke, but was also a reference to his participation in Kuorosota (the localized Finnish version of Clash of the Choirs) in 2010. Hietala was the master of the Kuopio choir in the program's second season. He came second in the contest, losing in the finals to the Joensuu choir, headed by pop rock singer Ilkka Alanko. Tarot's single "I Walk Forever," from the Gravity of Light album, was performed for the first time by Hietala, Tommi "Tuple" Salmela and the Kuopio choir during Kuorosota 2010; other songs performed included "The Phantom of the Opera," which Hietala has covered with Nightwish as well.

In June 2010, Hietala joined the heavy metal supergroup HAIL! on two occasions, performing Black Sabbath's Neon Knights with Ripper Owens, Andreas Kisser, James LoMenzo and Paul Bostaph at two of their shows in Finland.

On 14 August 2013 Hietala was the first singer to be confirmed by Arjen Lucassen to guest on Ayreon's new album The Theory of Everything.

Hietala has two children with his ex-wife Manki, twin boys Antto and Miro. He and his family currently live in Kuopio, Finland. When he is not touring, he enjoys reading books, playing video games, and watching movies. He especially likes fantasy, horror and science fiction books. In 2016, a Finnish newspaper reported that Hietala had filed for divorce. In August 2018 he married Camila Cavalcanti.

Hietala released his first solo album Mustan sydämen rovio in May 2019. He released the album under his birthname Marko Hietala and will be using the name also in his other projects in the future. Hietala has described his solo material as "hard prog". An English version of the album, titled Pyre of the Black Heart (Nuclear Blast), followed in January 2020. Joining him on the albums are drummer Anssi Nykänen, keyboardist Vili Ollila and guitarist Tuomas Wäinölä with whom he also toured in Finland in the summer and autum of 2019. The band will embark on a European tour in February 2020.
