Triarii is a one-man music project founded in 2004 by Christian Erdmann. Early experimentation with samples and distorted vocals led to the first single "Triumph" in 2004, released through Eternal Soul Records, establishing his signature pathetically grand sound. In 2005 he issued Ars Militaria and the single "Imperivm", marking a shift toward cinematic themes. Subsequent releases include Pièce Héroique (2006), Muse in Arms (2008), and Exile (2011). He also collaborated with Tomas Pettersson for "Roses 4 Rome" (2008), which led to joint project TriORE.
