After listening to the obvious and commercially marketed music of Korea and Japan (and getting tired of them), I kept youtubing and googling. And, boy, did I find some really good bands - Sleepy.ab (Japanese) , Peterpan Complex (Korean) and Nell (Korean). The former two totally have a Radiohead influence in their music and they do it well. My favourite is Nell, a South Korean indie band. I can't stop listening to 'Good Night'. Do listen to them and if you have any new music, please share them with me.
