Jukka Koskinen

Jukka Koskinen is a Finnish musician who is the bassist for the metal bands Wintersun, Nightwish and Crownshift. He was also the bassist for Norther from 2000 until their disbandment in 2012, for Amberian Dawn from 2010 until 2013, for Cain's Offering from 2009 until 2014 and for Dark Sarah in 2014. In May 2021, he was revealed as Nightwish's session bass player for the band's virtual performances and for their Human. :II: Nature. World Tour in 2021 and 2022, and later joined the band as their new permanent bass player in August 2022.[edit]

Jukka Koskinen is currently evaluated by the iFANN Global Fame Engine but does not hold a placement in the published rankings, meaning he sits outside the Global Top 1,000 and all scope-specific leaderboards. This absence of a numeric rank reflects his status as a highly respected musician whose fame remains deeply embedded within the specific communities of Nightwish and Wintersun rather than expanding into a standalone global celebrity tier. While his name carries weight among metal enthusiasts, the engine has not assigned him a position on the world stage at this moment.

His fanbase operates without a formal, unique moniker like 'The Choir' or 'Wintersunners.' Fans who follow Jukka simply identify as members of the broader Nightwish or Wintersun communities. There are no documented rituals, viral incidents, or organized campaigns dedicated solely to him that would suggest a distinct mythology. His integration into these groups was defined by professional reliability rather than grassroots mobilization. When he transitioned from a session player to a permanent member of Nightwish in August 2022, the reception was one of relief and acceptance within the existing family structure of the band's followers. He engages with this audience through standard channels like interviews and social media updates, sharing insights on his influences and upcoming tours. Notably, his performance with the supergroup Crownshift at Wacken Open Air in November 2025 further cemented his presence in major festival circuits where interaction occurs naturally. By June 2026, his decision to part ways with Crownshift to focus exclusively on Nightwish and Wintersun signaled a return to his core roots, reinforcing that his legacy is built on steady longevity across multiple acts rather than fleeting viral moments or legendary crowd disruptions.[edit]

Jukka Koskinen is a Finnish bassist known for his work with Wintersun, Nightwish, Crownshift, Norther, Amberian Dawn, Cain's Offering, and Dark Sarah. He served as the bassist for Norther from 2000 until their disbandment in 2012 and joined Nightwish as a session player in May 2021 before becoming their permanent bassist in August 2022. His live debut with Nightwish occurred in 2021, filling the role left by Marco Hietala after two decades with the band. In late 2025, he performed with Crownshift at Wacken Open Air, a supergroup featuring members from Nightwish, Finntroll, and Children of Bodom. However, by June 2026, he announced he had parted ways with Crownshift to dedicate his time exclusively to Nightwish and Wintersun. His rise to prominence was driven by official announcements rather than fan campaigns, and he is widely regarded as an exceedingly good bass player who successfully filled the shoes of a long-standing icon without controversy. Fans often describe his tenure as feeling like coming to a family during his initial interview with Chaoszine in June 2021.[edit]
