Mammoth Grinder, the band featuring bassist and vocalist Chris Ulsh (Innumerable Forms, Power Trip), guitarist Mark Bronzino (Iron Reagan, ANS) and drummer Ryan Parrish (Iron Reagan, ex-Darkest Hour), are now streaming a b-side from their 2018 record Comic Crypt called "Lunar Mass." The song is available only as a Decibel FlexiDisc that you can grab right here alongside their new issue.
As fo the song, it's filthy disgusting death metal.
