Dir En Grey (ディル・アン・グレイ, Diru an gurei?) is a Japanese metal band formed in 1997 and currently signed to Firewall Div., a sub-division of Free-Will. As of 2008, they have recorded seven full-length records and while the group's lineup has remained consistent since its inception, numerous stylistic changes have made the genre of their music difficult to determine (though it is generally considered to be a form of rock music). Originally a visual kei band, the band has opted for less dramatic attire in recent years.
Dir En Grey has toured through Asia, Europe, South America, and North America;Billboard commenting on the group's international fanbase, that the band "has transcended the language barrier in the United States through its music" and "gained its audience without singing in English".
