Singer Kim Tae Woo, who is currently promoting his title song Love Rain from his 2nd album T-Virus, will be featured in the OST for the drama IRIS! His song is titled Dreaming Dream (?? ??) and will be released on November 11 through the drama and music portal sites. Dreaming Dream is composed by Lee Hyun Seung, who composed the past two songs Love Of Iris and Do Not Forget from IRIS. Kim Tae Woo's song will be used as the theme song for character Kim Hyun Joon, played by actor Lee Byung Hun. Unlike the other IRIS OST tracks, this song will not be a love song and will portray an atmosphere of betrayal that goes along with the problems Kim Hyun Joon has to face. This track will be the 4th off of IRIS, following the recent track Love Is So... from December. Stay tuned to this week's episode of IRIS or the music portal sites to hear the song!
