Call of the Void, who used to be called Ironhorse before some trademark issues, blend crust punk, hardcore, and grind into cathartic, anthemic bursts. (It makes sense they were set to tour with Gaza and that their label mentions Converge.) To get an idea of the Boulder, Co., quartet's approach, take a listen to "Napalm Lungs",  from their debut album Dragged Down A Dead End Path, out March 19 on Relapse.
