Since I'm not all that well-versed in Kpop, I'm going to go with someone I've seen more recently as best live female singer. It's a girl group that I'm not into, but from what I've heard, they sound pretty damned good live, especially the one named Kim Boa. That would be the group SPICA.
Kim Boa is the one all the way to the right and from all reports, she used to be Infinite's vocal coach. Here she is with Infinite's Sunggyu singing "Lucky":
Don't they sound great??
Honorable mention goes to the Piggy Dolls.
