"Mass Extinction‘s debut is a ripping indictment of animal abuse and slaughter. With buzzsaw blasts and sludgy stomps, Mass Extinction’s crust-grind was written to serve as a sonic animal rights manifesto. Come for the riveting riffage and diseased vocals, and leave with a smile: all proceeds from the album’s digital sales are being donated to the Skylands Animal Sanctuary & Rescue in Wantage, NJ." - DECIBEL
