Yes, I actually have an update! Albeit a short one. Another metalguitarist.org find. A Tokyo-based death metal band. The singer/guitarist posted this video on the site and I watched it and pretty much fell in love with it. A nice Opeth sort of vibe to it, and builds up to perhaps some of the most ridiculous intensity I've ever heard in music.
Oh, and a fun-fact, the singer is the only guy in the band who speaks any English.
Thanks for reading, I'm off to see if I can find some more music from them.
