Dark Passion Play, due out October 2, is Nightwish's sixth release and its first since the departure of vocalist Tarja Turunen, who was dismissed very publicly by the band's other members in 2005.
To find her replacement, the group solicited demos from singers interested in the position, eventually choosing Olzon in the spring of 2006.
