YouTube will livestream a debut concert performance of Psy's hugely anticipated follow-up to his global hit Gangnam Style, the South Korean sensation has announced in a teasing video message.
The 35-year-old rapper appeared to do a snippet of what might be the next big dance craze, to go with his new single Gentleman, after his invisible Gangnam horse-riding dance that went viral with last year's breakout song.
A YouTube blog with a link to the video said a livestream of Saturday's concert at the Seoul World Cup Stadium will run from 6.30pm Korean time (9:30pm NZ), when Psy will "share his new single with the world".
In the one-minute video posted online, he said: "April 13, 2013 is a new single worldwide, all at the same time. And I'm going to do a concert in Korea ... and you can see it live on YouTube. Just for you," he tells the viewer.
The camera then pulls back and he launches into a brief bit of dance, in which he repeatedly swings one leg to the side, like kicking a soccer ball, while moving his arms from side to side, as if carrying a large bowl.
The new single Gentleman was to hit online music stores worldwide on Friday and finally answer the question of whether the Gangnam singer will be more than just a one-hit wonder.
A satire on the luxury lifestyle of Seoul's upscale Gangnam district, Gangnam Style has become the most-watched YouTube video of all time, registering more than 1.5 billion views since it debuted last July.
The song topped charts around the world, and inspired a horde of online tributes and parodies, as well as flash mobs of thousands of dancing fans in cities like Paris and Milan.
