An early opinion on Octahedron...
I'm mildly dissapointed. I know that The Mars Volta were going for a softer style here, but I wish they would have done more musically. It was almost lazy. Cotopaxi is an all-time great track however, and a lot of the slower tracks have nice melody nad are very enjoyable. I guess I just expected a little more out of them musically. This feels more like a Mars Volta EP than it does an album, if you know what I mean. I did, however, get a sort of classic prog vibe out of this album, and maybe that's what they wanted to do. Still a solid album, and I'll listen to it a few more times in order to get a more informed opinion.
Early rating: 7.5/10
Not album of the year material unfortunately.
