i've listened to ukiss since their man man ha ni. and in every live perf videos, kevin never fails to amaze me. but this concert is just amazing. his voice characters, his dance, and his perfect tone when singing WHILE dancing. You can hear him clearly even when he's jumping with kiseop. and he's not the only person being perfect in this group. If only in every other k-pop tv performances (not just concerts), they could use a minus one like this instead of playback, so that their real singing quality could be fully appreciated instead of just overlaying with the playback. of course, please don't overdo their voice either.
