Four years ago Mammoth Grinder released their last full length album, Extinction of Humanity. This album was released through Relapse and Cyclopean Records. The album showcased the band’s drive to devel into a distinctly death metal sound, full of aggression and with a punk flare. The band continued in this spirit on 2011’s split LP with fellow Austin, Texas-based Hatred Surge. Now they have joined with 20 Buck Spin for the release of their wildly anticipated third full length album Underworlds.
20 Buck Spin will release Underworlds on LP, CD and digital worldwide on July 23rd. Mammoth Grinder will 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.
