Ostraca is a three-piece hardcore / screamo band from Richmond, Virginia, formed in 2009. They are the next phase of a band that was once known as Kilgore Trout. Honing in the sounds of the historic screamo bands before them, such as Usurp Synapse, Circle Takes the Square, and City of Caterpillar; they play an intensely dark, chaotic and dissonant style of screamo/emoviolence that harkens back to their Virginia forefathers.
