It’s been nearly four years since the last MAMMOTH GRINDER full length Extinction Of Humanity was released via Relapse Records (CD) and Cyclopean Records (LP). That album showcased the band’s direction into a distinctly death metal permutation, full of aggression and punk rawness. The band continued in this spirit on 2011’s split LP with fellow Austin, Texas-based HATRED SURGE. Now in 2013, Mammoth Grinder has found a home on 20 Buck Spin for the release of their wildly destructive third full-length album Underworlds.

The album is adorned with artwork by the legendary Joe Petagno whose work has graced albums from artists like PINK FLOYD and LED ZEPPELIN to MOTÖRHEAD and MARDUK.

20 Buck Spin will expose the damaging Underworlds on LP, CD and digital worldwide on July 23rd, and Mammoth Grinder shall tour extensively upon the album’s release. In the meantime the band will play out regionally, providing support for the May 10th appearance of this year’s Decibel Magazine Tour featuring CANNIBAL CORPSE, NAPALM DEATH and IMMOLATION as it hits Houston, Texas, and a badass spot alongside MAGIC CIRCLE, Iron Lung, CRUCIAMENTUM, TRAGEDY and the almighty BOLT THROWER at this year’s Chaos In Tejas in MG’s hometown of Austin on Friday, May 31st.
