4minute, B2ST, and G.NA arrived at Heathrow Airport in London on December 4th, where more than 400 fans greeted them with cheers and applause. All of the Cube Entertainment artists arrived at 5:20pm with the exception of the Trouble Maker team of HyunA & Hyunseung who arrived a day later due to their performance on SBS 'Inkigayo'. As soon as the artists stepped out of the gate, the airport turned into chaos and pandemonium. An insider from Cube Entertainment informed OSEN during a recent phone interview, "The artists arrived at a time much later than actually scheduled, so we were shocked to see that so many fans were still there waiting to see them. The airport security officers did not stop the fans from running towards the artists and due to safety reasons, the Cube Family was unable to give their greeting they had previously prepared." Fan videos of the Cube Entertainment artists arriving at the airport have made their way onto Youtube, and are garnering attention from the public. Some fans even held up placards requesting to see a performance by Trouble Maker, less than a week after their debut. A staff member from the airport remarked that they were shocked; this was the first time fans have gathered in such a large number to see Korean artists. 'United Cube Concert' will be held at the O2 Brixton Academy in London at 7:30pm on December 5th. This is the first performance of their World Tour, and their next stop will be in Brazil.
