Epic cavern metal?
I kid, but that's what this is reminding me of, something that takes the notion of a sort of sci-fi metal and runs with it excluding being space metal. Actually, scratch that a bit, maybe it could. :)
I like the sheer deliciousness, depth and atmosphere of this track, it's really involving to the listener. In my opinion this is a fantastic setup that you have tweaked up here. Everything sounds balanced and righteous.
I like the guitar tone, it's exactly suitable for this reach of genre. Nice and grindy, chugging all fine too.
Drums are snappy, and definately up to par, I especially like the snare, nice!
The choir assembly also has benefited from this setup here, fantastic, it sounds really cavernous, mysterious, echo-influenced, all around deliciousness.
I must make note though that this is the first submission that I've heard of yours, so therefore I don't have a point of reference in terms of prior submissions to compare to, but this is alread suitable enough.
Please contact me if you would like to use this in a project. We can discuss the details.
