On the morning of August 10 KST, Junsu suddenly made an appearance at a club, making the guests go wild. It appears that he wanted to get the city of Busan pumped up for his Asia tour concert. Along with an American dance crew, Junsu put on an energetic stage with a remix of "Incredible". 

A rep commented, "We knew Junsu's tour would stop by Busan, so we booked him for this weekend. We plan to remix a lot of his dance songs. As last week marked the start of the vacation season, a lot of foreigners have been coming to the club, and when Junsu entered, the response was hot. Everyone took pictures and videos to put on their SNS."

One clubgoer said, "A siren went off, and he was there. I was so surprised. Oh my god! It was an incredible performance. It was all I could dream for. It was seriously an incredible night."

Busan is the fourth stop for Junsu's 'XIA 2nd Asia Tour Concert INCREDIBLE' on the 10th and 11th.
