Please Never Ever Stop Playing Guitar, Never Stop!
First of all, even a song this short needed vocals, but this guy put more than what a nine minute-long song would have. That's okay--the more, the merrier (as long as he doesn't trip on his words!) I always say--so what else is new?
Well, I don't know, but maybe the bass could use some extra chunk. It's just a personal preference. Not to nit-pick, but the biggest strength, those excellent melodic rhythms, might be hiding something.
Now, this guy is just plain awesome. There are a few trips on his words, just to make sure his voice is consistently harsh. However, the lyrics are just plain psycho--very reminiscent of (and I feel like such a fucking game geek for bringing this one out) Delita Hyral from Final Fantasy Tactics, or perhaps the creeps he allegedly serves--and since the song loops without any struggle, it makes for the best damned melodramatic boss fighting music, like if someone around the portal designed an online-ready 2D fighting game with medieval fantasy themes... then this would be the Black Fell Knight Motherfucker final boss character.
Overall, there isn't much to complain about, and even if there was, we're too busy headbanging to the song without realizing that it loops flawlessly and transforms the thing into twenty minutes of migraine joy. Excellent work.
