What will undoubtedly be an extraordinary concert, also boasts quite an extraordinary budget.

Psy's upcoming concert [Happening], set for April 13th, is costing 3 billion won to happen. That kind of funding will ensure the highest quality visual effects, including huge LED screens for even the furthest back fan to get a good view.

The show is gaining all the more attention because the world star will be unveiling his new song following last year's global hit "Gangnam Style".

50,000 fans are expected to come to watch the performance, which will also be streaming live on YouTube.
