I once saw a little-known power metal band called ARCTIC FLAME open up for the granddaddies of the genre, GAMMA RAY, back in, oh, about 2010. By metal standards, the entire band might as well have pensioner passes; every single one of the band members must have been in his late thirties to early forties. Yet there was no denying that they could play; the song that I remember the best, even after all of these years, is still their superb "Lord of the Wasteland", with its epic, anthemic chorus:
