Formed in 2006 in Austin, TX, and consisting of current and former members of Power Trip, Iron Reagan, and Darkest Hour, MAMMOTH GRINDER play a primitive brand of punk-inflected death metal. The band has released three blistering full-lengths and numerous splits and EPs since forming over a decade ago. After a brief hiatus in 2014, MAMMOTH GRINDER have returned and signed to Relapse Records to wreak havoc once again on the underground.

Now in 2018, MAMMOTH GRINDER return after five long years with their fourth full-length Cosmic Crypt, a non-stop, meteoric force of aggression and mayhem. Recorded by Chris Pierce and the band at Trax East in South River, NJ, mixed by Arthur Rizk (Power Trip, Sepultura, Inquisition) and mastered by Toxic Holocaust’s Joel Grind, Frontman Chris Ulsh (Power Trip, Impalers) recruited Mark Bronzino (Iron Reagan) and Ryan Parrish (Iron Reagan, ex-Darkest Hour) to take MAMMOTH GRINDER to new heights of misanthropic rage and blazing songcraft! Features stunning cover art from the legendary Joe Petagno (Motorhead, Autopsy, Angelcorpse, Pink Floyd)
