Later when they were signed to Tooth & Nail Records, they changed the name of the band to "The Letter Black". In 2008, Sarah Anthony was featured on the Pillar album For the Love of the Game, singing on the track "I Fade Away". The band often does 150 shows or more a year and has shared the stage with bands such as Skillet, Decyfer Down, RED, and Hawk Nelson.
