i think hikki has great lives...but they're not as entertaining as say...
kuu, whose voice isn't always that great, but her performances are damn fun to watch. And she's always so happy afterward.
ayu has the best concerts. ever. hands down.
namie is cool live...but some of her lives bug me because of the vocal track things. whats up with those?
there's a lot of people I havent seen live...so...sorry for not picking more.
oops...i forgot about mink
she's an awesome live singer.
