Seoul: South Korean singer Psy is set to release his first album for more than three years, with the “Gangnam Style” star vowing a return “to his roots”, his agency said Tuesday.

The quirky singer/rapper was catapulted to global stardom in 2012 after his “Gangnam Style” music video, with its invisible horse-riding dance, went viral.

It remains the most-watched video of all time on YouTube with more than 2.4 billion views.

But the two singles he released since then—“Gentleman” in April 2013 and “Hangover” in collaboration with US rapper Snoop Dogg in June 2014 -- received a relatively lukewarm response from fans. 

Now the 37-year-old is set to release his new album on December 1 -- the first since July 2012 -- YG Entertainment said in a statement. 

“Psy said late last year... that he would ‘go back to his roots and return with a new album’, and anticipation is running high,” the statement said.

Before “Gangnam Style” conquered the world, Psy was already an established artist in South Korea, with a reputation for provocative lyrics and rambunctious stage performances peppered with profanity and fueled by numerous bottles of the South Korean liquor soju.

Some fans felt that the singer lost his edge after travelling the world, riding the “Gangnam Style” wave and being feted by everyone from world leaders to sports stars and business tycoons.

At the time, Psy himself voiced fatigue with the hype.

“Sometimes, honestly, yes I get tired or I get sick of it,” the rapper said in Singapore, during one of his endless overseas promotional stops.

He has kept a low profile for the past year while working on the new album—the seventh since he started his music career back in 2001.
