I have been looking for this release.
IRIS Original Soundtrack Perfect Box TV Original Soundtrack [CD] (http://www.cdjapan.co.jp/detailview.html?KEY=CMCC-9459)

It has 4 new score tracks. I was able to hit down the new vocal songs of Lee Byung, but I am much more interested in the score tracks.

Please, can someone help me here.

Thanks in advance.
