Sonata Arctica is a Finnish power metal band from the town of Kemi, Finland. Created as a hard rock band named Tricky Beans, they later changed to Tricky Means and finally to Sonata Arctica, when they shifted to power metal. They often include symphonic metal elements, and their later releases contain several elements typical of progressive metal, as well. The current line-up consists of singer, keyboardist and songwriter Tony Kakko, guitarist Elias Viljanen, bass guitarist Pasi Kauppinen, keyboardist and keytarist Henrik Klingenberg, and drummer Tommy Portimo. All the musicians of the band's history except Portimo also acted as backing vocalists.

As of 2014, the band has released eight full-length albums (three via Spinefarm Records and five via Nuclear Blast), their most recent being, Pariah's Child, on March 28, 2014.
