after watching a few artistes performing on music station, i just realised how important it is to be able to sing live. many jap artistes who make it big, unfortunately, cannot sing that well live. (ok, maybe i'm just being picky, but i do think that an artiste should ensure, to the best of his/her ability, that every performance is perfect.)
in any case, crystal kay really good. i mean, she's hitting all the right notes. kinda reminds me of american idol.
oh well, heard she's korean/african-american who grew up in japan. you can catch her performance on music station at the following address (but login to crunchyroll first!):
