Encyclopedia of American Traitors was a hardcore punk band from Pennsylvania. They broke up in '99. They played a mix of thrashy punk shit and hardcore that could today be considered screamo or even emo violence. Like most of these bands from a decade ago the genre(s) of music that they are associated with really didn't exist in their time. Their songs include political sound clips and have very strong lyrics that support their political views. A lot of their material seems to involve labor. They did splits with Orchid and Kwisatz Haderach, were featured on two compilations and put out two LPs.
