Rock band NELL surprised many of their fans and held a concert, 'SECRET STAGE.'

On September 3, vocalist Kim Jong Wan hinted on his SNS, "I want to perform." Many of his fans retweeted the statement.

Then, on September 10, NELL announced a concert with a hand-written message.

On September 13, NELL held their concert at the Seoul Lotte Card Art Center. The tickets were sold onsite rather than online.

A related staff member from their agency said NELL prepared the stages in a hurry but showed a perfected performance for their fans who were due for a nice surprise.
