The term is often discussed along with Aristotle's concept of anagnorisis. In "Poetics", Aristotle discusses many key concepts of drama, such as anagnorisis and catharsis. In late 2015, the duo released the single "Anagnorisis", which was produced by Rhys Fulber. Anagnorisis (born in Kiev) is a German producer, songwriter, and musician. Anagnorisis, however, is not limited to classical or Elizabethan sources. Anagnorisis also writes movie soundtracks and background music for diverse film productions. Aristotle considered anagnorisis, leading to peripeteia, the mark of a superior tragedy. Since year 2008, Anagnorisis works on some electronic projects (EBM, electro-industrial, psy trance). "Anagnorisis" was released as a 7-inch single in 2015 with the B-side "Shift of Dismay".
