I'm a bit confused here, isn't her name spelled 'Younha' as in the official web site address:
http://www.younha.net/ ? Or is that just the way the Koreans spell it? Oh well, what's more important is the music, i was watching a recent Melodix! episode (looking forward to Ami Suzuki's perf.) but it was this newcomer who caught my attention. Must've been that rock guitar + piano = killer combo!
I have her Houki Boshi pv on repeat now, i'll upload that and a live version soon.
