So, I was listening to the Wagakki Band and this appeared on the side-bar. Interesting juxtaposition.
Blind Guardian is better known as a heavy metal/speed metal group, but they also do, well, Tolkien-rock and things like this. It’s a sign of a good song that you can strip out the genre cues and it is still catchy and memorable. I suspect it will appear in a Familiars book.
