“This is the album metalheads have been craving! No cookie cutter, pre fab crap we hear pushed on the radio, no bands copying sounds of other bands because they feel it will sell, this is an album celebrating metal, with some of the best in the business at the helm. It doesn't get much better than this, kids!”
