Wandmacher was born in Minneapolis. He began his career composing music for local news media and television commercials before scoring short and feature films by local filmmakers. While following a series of email exchanges that started via a film music newsgroup, Wandmacher met Alan Silvestri and was invited to Los Angeles to participate in several scoring sessions. They composed music for the English-language releases of several Jackie Chan films including Armour of God and Drunken Master II. He eventually found success with the black comedy horror film Modern Vampires. Wandmacher co-composed the score with Danny Elfman, the brother of the film's director Richard Elfman. Wandmacher permanently relocated to Los Angeles.

I have to admit that in the past I've not been overly struck by Wandmacher's work, so it was great to finally see a project where he's allowed to flex his creative muscles and deliver something a little more in depth than clichéd horror fare.
