Little Boots has been added to the line-up for Denmark's finest.
The emerging British pop talent is to be joined at the festival by New Jersey rock outfit The Gaslight Anthem, who are set for an increasingly busy summer.
Roskilde was thought to have completed its line-up a couple of weeks ago but a few more spots are still open for some more musical surprises.
The monster bill for the festival brings together the likes of Oasis, Coldplay, Faith No More and Nine Inch Nails as well as Slipknot, Pet Shop Boys and the mighty Kanye West.
