Alright so after further listening to Octahedron, I've decided it's not as bad as I originally thought.
Is it TMV's worst album? In my eyes, absolutely.
Does that mean it's bad? Not really.
It may grow on me more, but I think it will always be my least favorite (of all the current releases). Cotopaxi is my favorite song, but it feels so out of place. I think everything is fairly consistent, just it very rarely reaches the greatness they've often had nearly all the way through their older albums, in my opinion.
Also, to be more on topic, I just got Maldoror - She.
