SAME

There's a lot of boy and girl bands that can do it too

Girl you need to check more second generation artist. They had to sing live most of the time with no back track. Big bang was very known to use hardly any back track mainly just to cover the chorus so they could run around and hype the crowd. 2 am could sing without there in ear monitors in which was a very hard thing to do because sound can bounce around in a studio and disorientate you with how far behind the song you are hearing it. Kara, wonder girls, Girls Generation, 2ne1 and sistar, where very well known to do full choreography with a hand held microphone and live vocals. You could hear there jewelry banging around alot of the time. BoA can do a whole choreography set like her song eat you up by herself with a hand held mic and still sound as flawless as ever.

Mamamoo too
