Nier is an action role-playing video game developed by Cavia and published by Square Enix in 2010. The music of Nier was composed by Keiichi Okabe with members of his studio, Monaca, Kakeru Ishihama and Keigo Hoashi, and Takafumi Nishimura of Cavia. The soundtrack has inspired the release of four official albums by Square Enix—an official soundtrack album and three albums of arrangements—along with two mini-albums included as pre-order bonuses for the Japanese versions of the game and two licensed EPs of jazz arrangements.
