These shows are at the pizzerias right? Cuz that's exactly when the time would be oppertune for say, overwhelming torturous screaming. If they are doing what I think they are, they are intentionally scaring the sacrifices before death. Terrorizing intentionally bluntly. There is a 909 mixer used by the band, I hear that right off. Meaning, constant sound, never a moment during a set for a "quiet" pause.
