The vocals have that boisterous musicality that are what you might expect from such a group. Guitar solos show the hammering-on rapidity so much a part of the technical bag of accomplished players these days, but do not over rely upon speed.
The full impact of the band in their fully arranged music is what stands out as a whole in the end. HeKz will satisfy your need for something heavy and well put-together. A winner for those who enjoy the genre!
