Nightwish's Tuomas Holopainen on symphonic metal and the band's new film, Imagineaerum

Formed in 1996, Nightwish gained instant popularity in its native Finland with the 1997 release of its first album, Angels Fall First. Eventually, Nightwish achieved international success with album sales in excess of over eight million worldwide, yet the group has struggled to achieve popularity and recognition here in the States. Nightwish delivers chugging distorted guitars, double-bass kicks, fast tempos and time changes -- the signature traits of any metal band. But the act's songs also include classical structures and arrangements and have featured an orchestra and a choir, bolstering a classically trained female vocalist -- all of which has earned it a "symphonic metal" designation, a tag its members are comfortable with.
