A friend I grew up with found Sabaton six years ago, and thought “I bet Red knows this group!”
I didn’t, but now have all their stuff, most of Nightwish’s stuff, the Hu’s, and a lot of the newer power metal.
Wardunna surprised me, and I have enjoyed the Viking folk music.
Check out Saltatio Mortis for some interesting stuff. My Mother Told Me and Brunhild are a couple of great pieces.
