[talk] This is Song Ga-in, who has made a mark in the trot world with her song "Daedonggang."

This is a live performance that was suspected of having played a CD as soon as the first verse was sung.

Everyone's eyes widen at the breathtaking live performance.

It's really perfect, even down to the explosive high notes in the chorus.

This shock doesn't seem to fade even after a few more years.
