ソナタ・アークティカ
Elias Viljanen traveled with the band Sonata Arctica in 2007, filling in for their guitarist Jani Liimatainen on tour. On August 8, Sonata Arctica formally released a letter naming Viljanen the official guitarist in Sonata Arctica. Liimatainen had apparently not been fulfilling his mandatory civic duties as declared by the Finnish government, and this had caused a rift in between him and the other members of the band. Viljanen took up the mantle as guitarist with much controversy, with many hard-core fans still wanting Liimatainen to be a part of the project. But Sonata Arctica were adamant, as was Liimatainen, and Viljanen thus maintained his status.
