Former 'Superstar K2' contestant Jang Jae In held an impromptu folk concert on the streets of Seoul last night. The guerilla concert started at 7:30 PM and despite a slight rain, fans and passers-by crowded around the singer as she performed songs from her debut album, 'Day Breaker'. The songs were received enthusiastically by the audience, as they clapped after each one. After the concert, Jang Jae In commented on her Twitter, "The streets of Kang-Nam [a district in Seoul], I want to thank the audience who heard my music in the rain. It's pouring. I felt a little bad! I hope you have a nice night and return safely." Jang's agency Kiwi Music stated, "It looked like it was going to rain, so we were considering canceling the concert, but she had such a strong opinion about it, so we ended up having the concert anyway."
