I've always loved Korean indie/folk music, particularly Adultchild (어른아이), but this album, 보옴이 오면 ("Boomyi Comes"), is really touching to me.
Bluedawn is a Korean folk duo consisting of Dawn and Sorrow. Their sound isn't exclusively melancholic and gentle, as there are more cheerful songs too. 보옴이 오면 is the group's third album, and my favorite. The other two are beautiful as well, but this album's beauty reaches a much deeper level. Bluedawn was a part of the Pastel Music label, which has released some really incredible music... I highly recommend both them and this album.
