Hip hop idol group Block B will be holding a showcase and a fan meeting with their BBCs, just one day before the release of their 3rd mini album, 'Welcome to the Block'.

Although the showcase was only advertised through their fanclub and SNS, all 2,000 seats were reportedly sold out 24 seconds after they went on sale!

Additionally, 100 fans from Block B's Japanese fan club scheduled a visit to Korea just for the showcase, and so Brand New Stardom decided to prepare seats for them as well.

The showcase will be attended by 100 reporters from Taiwan, the Philippines, Singapore, Thailand, and other parts of Asia. Since Block B had actively promoted in various parts of Asia in 2011, the effect they've had overseas will be demonstrated through this event.

Fans will not only get to see the music video for the very first time, but they'll also be given the opportunity to take photos with the members as well as participate in P.O.'s birthday party event.

Block B is currently carrying out their activities in Thailand, but will return soon before their new mini album drops on February 2nd.
