Sabaton is a Swedish, Power-Metal band from Falun. Don't worry, they sing in English. They are apparently gearing up for a tour in 2022, and have released a couple of new videos. Most were from old albums. This one, looks to be new. I expect that means that an album will be forthcoming, but I can't find any reference to it yet.
The lyrics are in the video, but I usually have no trouble understanding Joakim "Jocke" Brodén; he is singing fairly clearly given that this IS metal. It you want the lyrics, they can be found at this link.
This song Is Kingdom Come by Sabaton. It was released as a single on July 16th. As far as I can tell, it is not part of an album, though my knowledge of Sabaton is not encyclopedic.
