I don't understand how this album has received almost no attention from the metal community. It's predecessor, 2006's Magla, made a little bit of a splash, yet outside of a couple gushing Metal Archives reviews, no one seems to care. Personally, I feel that Umro is a far superior work, and stands as the best thing The Stone has yet released. It's a dark motherfucker, full of brooding atmospheres and chaotic atonal riffing, yet nonetheless possesses a ton of distinct, memorable melodies. Needless to say, I fucking dig it, and if you are a fan of super dark, technically proficient, out-there black metal, you will too.
Grayceon is a three piece metal band consisting of drums, guitar, and electric cello. Their music isn't actually as out-there as you might think, though tends to be difficult to pin to a specific genre- similar, in a way, to Hammers of Misfortune. I got to see them a year or so ago and they put on a stellar show. Go see them if you can, otherwise check out this album.
Here's another gem that I haven't seen get nearly enough recognition. It's definitely not for everyone, but if you can get past the strangeness of it, there's some truly beautiful things to behold. Highly recommended.
