Hellshock is a crust band from Portland, Oregon that was formed in 2000. Sonically, they take a dark and heavy crust punk style and mix it with thrash and death metal elements, a practice which has been dubbed as 'stenchcore' by crust fans. Lyrically, the band writes almost exclusively about war. The five-piece has ex-members of Remains of the Day, Atrocious Madness, From Ashes Rise, and Detestation. The band is still active today. Their band name appears to be a play on the term 'shellshock' which refers to war-induced PTSD. War is Hell on Earth.
