If I recall correctly, the composer is not credited because he doesn't want to be, at least at the moment.
But that's something the dev needs to confirm because I read that a long time ago.

Is the music by John sleep dessert? Don't know anything about copy rights so don't want to reveal too much.

Haha glad to hear it. Nah it's not by John sleep dessert. (Who is that? I couldn't find them.)

Anyway maybe I can convince the artist to do a reveal eventually... Until then if you want more music like the trailer you should check out Chicago footwork and its offshoots. If you don't know about this genre you can start with late great DJ Rashad
