The video introduces Sam Lee who has worked on such large projects such as DJMAX, GROOVE and Magna Carta to name a few. There is also composer Roh Hyeongwoo and vocal directors JJ & Chris which created the ensemble heard in the most recent trailer. The vocals for the title music were sung by Naimee Coleman which shows a growing relationship between Eastern and Western musicians both in the gaming industry and recently the filming industry.
Hopefully they will be releasing more from this OST as such a great number of big names are working on it which should mean some high quality stuff for us to enjoy.
