One of the world's best opera singers, Paul Potts, will take part in OST for the historical drama Queen SeonDuk. He will be singing Dukman and Yoosin's love theme song called, "Step by Step", also called, "Passo Dopo Passo" in Italian. The meaning of "Step by Step" has an image of "slowly walking step by step without knowing where you are going". Since drama is popular, it looks like the OST will be a big hit as well. With OST staff from hit-drama "Dae Jang Geum" and "White Tower" taking part in Queen Seon Duk's album, not to mention singers such as Hong Kwang Ho, Lee So Jung, and IU, it looks like this album will be full of great tracks. Stay tuned to the release of Queen Seon Duk OST album on the 15th.
