Swedish bashers SABATON have announced details regarding their upcoming album, Carolus Rex, tentatively due for release in the spring via Nuclear Blast Records.

A new band update reads: "This album will be all about the Swedish Empire and for the first time ever we have had an expert to help us out with the theme, the well known Swedish historian Bengt Liljegren. We have also added some extra time in the studio to find the absolute right sound on Carolus Rex, and our producer Peter Tägtgren (HYPOCRISY, PAIN) says that this album will mark a brand new standard for how a heavy metal album should sound like! Carolus Rex will be out in May and after that we have a two-year long world tour to look forward to!"
