It should be noted that in case of capitalizations that Artist Intent comes first:
"When capitalizing song titles, album titles, or artist names, the appropriate grammatical rules for the language the text is written in should be applied _unless it can be shown that that the artist wishes the capitalization to be grammatically incorrect_, in which case the artist's version of the title or name is the correct one to use."
Dir En Grey (stylized as DIR EN GREY and previously as Dir en grey) is a Japanese heavy metal band formed in 1997 and currently signed to Firewall Div., a sub-division of Free-Will. With a lineup consisting of vocalist Kyo, guitarists Kaoru and Die, bassist Toshiya and drummer Shinya, they have released nine full-length records. Numerous stylistic changes have made the genre of their music difficult to determine, though it is generally considered to be a form of metal. Originally a visual kei band, the members opted for less dramatic attire for several years. The band has continued to have some sort of visual orientation, such as hairstyle or clothing, but have ceased with wearing female clothing.
