CNBLUE has completely sold out tickets to their 4th concert.

CNBLUE have sold out all the tickets for every concert they have held so far. CNBLUE will be holding their concert '2012 CNBLUE Live Blue Night in Seoul' on December 15th and 16th. On November 6th, tickets went up for sale and all 8000 tickets were sold out within 10 minutes. Not only that, but as soon as the official sales opened, so many fans tried to access the site at once and the servers had trouble handling the surge in traffic and was inaccesible for a lot of fans.

FNC Entertainment said, "This solo concert 'Blue Night' is to properly end 2012 and to give back to the fans for their unchanging love. The members are preparing hard for the concert."

CNBLUE is also currently planning to comeback with a new album in January 2013.
