I'd never even heard of this before I stumbled upon it on Spotify. Not exceptionally metal, but this is hauntingly beautiful:
Yeah, that's Devin's country rock side-project. It's good, but I don't think it's as good as any of his solo albums. One that is kind of similar to it is Devin's album "Ghost," which is straight up ambient music. It's pretty awesome, though.
Check this out if you haven't before.
(the actual song starts around 0:42 if you're feeling impatient )
Very mellow, beautiful song that just builds.
