Lower Than Atlantis started out on Sumerian, so no.
I personally like it but I find all of the bitching in the YouTube comments hilarious. Hey, I like After The Burial/Veil Of Maya/The Faceless/Structures etc just as much as you do, but I also don't limit myself to that sort of music. I couldn't give less of a shit about being "metal" or having "metal taste" or whatever, I just like what I like.
i am looking forward to the album
