ソナタ・アークティカ
In early 2005, Nightwish invited the band to open the concerts of their North American tour. This tour eventually got cancelled, but the members of Sonata Arctica opted to still make a short tour, playing concerts in Canada and the United States. On October 21, 2005, Sonata Arctica opened for Nightwish at the Hartwall Areena, Helsinki.
