Dir en grey is a Japanese ban formed in 1997 and currently signed to Firewall Div., a sub-division of Free-Will. As of 2008, they have released six full-length records and while the group's lineup has remained consistent since its inception, numerous stylistic changes have made its music's genre difficult to determine (though it is generally considered to be a form of rock music). Originally part of Japan's visual kei movement, the band has opted for less flamboyant attire in recent years.
