North Korean leader Kim Jong-un watched a rare performance by South Korean musicians in Pyongyang. 

A South Korean art troupe that included girl band Red Velvet put on a two-hour show before an audience of about 15-hundred at the East Pyongyang Grand Theater on Sunday evening.

Kim watched the performance with his wife, Ri Sol-ju, his sister Kim Yo-jong and top North Korean officials.

Kim met with the performers after the concert, shook their hands and posed for photos.  

According to South Korean performers, he said that the two Koreas should hold cultural performances more often, proposing another event is held in Seoul around fall under the title "Autumn Comes." Sunday's concert was held under the title "Spring Comes." 

Kim also expressed gratitude to the performers for providing Pyongyang citizens with "this gift."

The opening time of the concert was changed multiple times, apparently to accommodate Kim's surprise attendance. It was originally set to start at 5:30 p.m. but was changed to 7:30 p.m. and eventually to 6:30 p.m. 

The South Korean musicians will jointly perform with North Korean artists at the Ryugyong Jong Ju Yong Gymnasium on Tuesday before returning later that day.
