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 (previously stylized as Dir en grey) is a Japanese metal band formed in 1997 and currently signed to Firewall Div., a sub-division of Free-Will. As of 2014, they have recorded nine full-length records with a lineup 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 metal. Originally a visual kei band, the band has opted for less dramatic attire in recent years.
