"The Wind is Blowing (바람이 분다)" is a 2004 Rock Ballad song by Lee So-ra. It is one of the classic Korean hit songs that, arguably, every Korean has heard of. (Teenagers might know it as well since it was covered by so many other singers.)
Lee So-ra is probably my favorite female singer from the "older" generation. (She is 50 now.) But her voice and color are so unique that I don't feel like her music is old at all.
If you are curious about her color, check out "The Wind is Blowing" by Lee So-ra.
