Before his foray into video games, Corelitz had worked on various commercials with composition studio, Steve Ford Music.
"[3] With that in mind, Corelitz based the score around an assortment of strings and percussion which included harps, violins and marimbas mixed with electronic elements.
"[4] In 2017, Corelitz was hired by Ludvig Forssell, composer for Death Stranding to assist him in creating sounds for the game.
The collaboration later led Corelitz to write additional music citing the studio's preference to "keep things fresh and different".
