When I saw the "K-Music" topic, my first thought, surprisingly, was Pansori. 

I adore this genre, the expression and powerful voice of sorikkun (singer of Pansori), the way the story is told through the song. 

Here you can see a boy on a buk (korean drum) and a girl with a fan performing Sugungga (수궁가), which is my favorite! 

In the background you can notice the meeting between the rabbit and the turtle, who invites him to visit the sea palace. 

Also I have pictured a dragon-king,who wants a rabbit's liver.
