The Devil Wears Prada is a popular American metalcore band from Dayton, Ohio. I found that the 45th Street location you mentioned refers to the band's early days.
The Devil Wears Prada's original name was 'The Dover's Crew,' but the name was later changed to 'The Black Bullet Theory.' However, in 2005, they changed the name again to 'The Devil Wears Prada,' a reference to the 2003 novel 'The Devil Wears Prada' by Lauren Weisberger.
45th Street in question would be 45th Street in Dayton, Ohio, where The Devil Wears Prada was formed.
