xDISCIPLEx A.D. Bio Heaven And Hell is destined to be a classic in more ways then one. The infamous Lake Effect Hardcore scene of Erie, PA spawns one of the most refreshing bands to hit the scene, xDISCIPLEx A.D. (Formally known as xDISCIPLEx). Their brand of hardcore combines powerful guitars, gritty vocals, and brutal breakdowns all with a positive Christian/straightedge message. Even in your home xDISCIPLEx A.D. will have you starting a pit, moshing your friends, brothers and sisters into the ground.
