Niilo Sevänen

Sevänen grew up on the coast of Finland in the town of Turku, before moving to Joensuu where he was raised. In 1994, he began learning the bass guitar and formed his first band: a punk rock act called Paise. The following year, the band changed its name to Stonecrow and began to shift its musical style. Sevänen left the band two years later due to musical differences. However, following his departure, he quickly collaborated with musicians whose interests aligned themselves with Sevänen and formed the melodic death metal band Insomnium.[2]

Sevänen grew up listening to a variety of hard rock, glam metal, grunge and heavy metal bands, among them Queen, Aerosmith, Sepultura and Metallica.[2]

Sevänen is, outside Insomnium, the director of culture in Kotka, Finland. He organises, amongst others, the Kotka Maritime Festival. He also majored in history of culture and literature.[3]
It is speculated that he did the vocals for Belzebubs' album "Pantheon Of The Nightside Gods". Fictional black metal band from JP Ahonen's comics "Belzebubs". This is yet to be confirmed by the author as he is in talks for "live" shows of the band, similar to the ones of Gorillaz and Dethklok.
