Liberteer is the solo grindcore project of Santa Cruz, California musician Matthew Widener, better known for his work in Exhumed and Cretin, formed around 2011. Their sole album Better to Die on Your Feet Than Live on Your Knees (2012, Relapse Records) is a dense political statement rooted in anarchist philosophy, notable for grafting brass instruments, banjo, and mandolin onto a blasting death-grind foundation.
