New Orleans’ EYEHATEGOD is the snarling, bilious sound of dead-end America. Since 1988, they’ve been a soundtrack for the troubled masses. Ugly music for ugly times. That’s the sense of disenchantment and disease that lies the heart of their latest and sixth full-length album, A History of Nomadic Behavior. Anyone familiar with EHG’s story knows this is survivor’s music, a sound unto itself where Sabbathian riffs are meted out with a caustic anger that goes beyond punk.
