Afterglow Of Ragnarok literally means aftermath of apocalypse. The protagonist (Necropolis?) is being called upon from an alternate dimension/future and is showed his world's fate (I'm basing all this without knowing anything about the comics). Man, Bruce is going full Seventh Son with the concept in this one!
Musicwise, a decent opener. The main riff got a good groove in it, the pre-chorus/chorus is full Senjutsu Maiden, atleast to me. But when the solo was about to begin, I expected something interesting but it ended abruptly... Actually I'm cool that they are putting so much effort in the videos (only the parts with Bruce on them are hilarious).
