K-pop starlet IU gave her first solo concert on Saturday, four years after she made her debut with the mini-album "Lost and Found."

She appeared at Kyunghee University's Peace Hall in front of an audience of 4,500 and sang 24 songs during the three-hour show. The concert showed her potential to develop as a great musician, rather than just a pretty face of pop.

"I think now I realize what it takes to be on stage," said IU, who was overwhelmed by emotions towards the end of the concert.
