Auri is a Finnish band composed of vocalist and violist Johanna Kurkela (Tuomas's wife), keyboardist and backing vocalist Tuomas Holopainen, and guitarist, keyboardist and pipe player Troy Donockley. Holopainen and Donockley are also members of Finnish band Nightwish. Holopainen described Auri's style as "rabbit hole music and celestial metal" with "influences from folk music, Celtic music, [and] soundtracks". Prog describes the band as prog folk. The band's name is based on a female character from Patrick Rothfuss' The Kingkiller Chronicle.
