Mammoth Grinder unleashes seven tracks of charging death metal with their 2009 effort 'Extinction of Humanity', akin to the classic early eras of Entombed, Dismember or Autopsy, combined with the bolting hardcore speed of Discharge. Armed with a recording driven by chainsaw guitars, screeching noise, and quaking drums, these Austin, Texas natives carve out a sound equally appealing to fans of metal and hardcore punk alike.
