More details about Goo Hye Sun's debut music album has been released by YG Entertainment today. YG Entertainment said on the 4th, "Goo Hye Sun made her debut as an actress and has recently showed everyone her many talents through directing a short film, writing a novel, having her own art exhibition, etc. She will go one step further by releasing her own personal music album at the end of August." They added, "The songs that are included on the album will be used for her first full-length movie which will begin filming at the end of the year. Goo Hye Sun personally wrote and composed all the songs, showing us her music talent in this area. OSTs (official soundtracks) are usually released after the movie is aired in cinemas, but in this case, because the movie is a music-related story, Goo Hye Sun hopes to release the music to let viewers preview it first before watching the movie." YG Entertainment also revealed that famous Japanese entertainer, Isao Sasaki had participated in Goo Hye Sun's album by playing the instruments. He will also be in attendance during Goo Hye Sun's album release commemorative concert called Over The Rainbow on 5th September, to show his support for her.
