Northern Kings was a Finnish symphonic metal cover supergroup, made up of four well known musicians: Jarkko Ahola from Teräsbetoni, ex-Dreamtale, Marco Hietala from Nightwish and Tarot, Tony Kakko from Sonata Arctica and Juha-Pekka Leppäluoto from Charon and Harmaja.
Marco Hietala is not from Nightwish and Sonata Arctica.
Actually, Marco Hietala is from Nightwish and Tarot, not Sonata Arctica. The model was fooled because the statement was half righ.
