This is a very good soundtrack. In my opinion the soundtrack had similarities to the soundtracks from Park Chan Wook Movie's (For Example: Oldboy, Lady Veangeance), which were composed by Jo Yeong-Wook. When you like this Ost, you should try the Ost's by Jo Yeong-Wook, which can also be find on this forum.
