Music like E.S. Posthumus

E.S. Posthumus was an independent music group that produced a form of 21st-century classical music/epic music that intertwined popular style drum rhythms 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 is meant to represent "all things past", suggesting the music was inspired by things that have ended, some time after they ended.
