Query: Zao is back

What an incredible album to come out of such confusion. Zao has manned up once again and are back with avengeance. Scott and Russ, two incredible guitarists, have seemed to stray away from the more technical side of metal and just bring it hard and heavy with some thoroughly enjoyable riffs. Dan is as good as ever on vocals. The Funeral of God also has a very interesting theme that is present throughout the entire album. Zao has put much work into this release and it definately shows. Buy it.
