I think the kids call this powerviolence? Nevermind the genre and call it whatever you like, but Tucson, Arizona's SEX PRISONER are nothing if not powerful and violent sounding music. At the onset of each song, rumbling noise gives way to a rush of low end roar and churning rhythms that fail to identify themselves with seemingly needless things like "riffs" or "songs." SEX PRISONER just attack, and the aftermath is left for the listener to dig through and try to discern some kind of meaning. This is what happens when you build a city where there is no water: people get frustrated.
