Mortal Treason began in Hartselle, Alabama and released two albums under Flicker Records. Their first album was titled A Call to the Martyrs and had more of a traditional Metalcore style. Their second album was titled Sunrise Over a Sea of Blood, which contained more elements of Death metal. The band has of late split up. Members of the band said that they believed "God has something else planned for us", but there were also rumors of label problems. On September 11, 2005 Seth Kimbrough officially announced their disestablishment.
