E.S. Posthumus (also known as "ES Posthumous") is an independent music group that produces cinematic style music. It is a form of epic classical that fuses intertwined drum beats with orchestral and electronic sounds. Their music is inspired by the Pythagorean Philosophy which states that "music is the harmonization of opposites; the conciliation of warring elements". The E.S. is an acronym for "Experimental Sounds" while Posthumus is a word that represents "all things past".   Wikipedia
