Scooter Braun is the guy behind Justin Bieber. He's also the guy who helped break PSY and "Gangnam Style" in North America.
Here's the story from Billboard:
On the afternoon Aug. 15, Korean rapper PSY and the overseas business manager from his record label, YG Entertainment, arrived in Los Angeles after a 13-hour flight from Seoul. At LAX, they were greeted by a smattering of fans and YG's American rep, who ushered them into a waiting car. PSY was going to Hollywood.
As his ride rolled through L.A. traffic, PSY, aka Park Jae-sang, cheerfully reflected on his whirlwind summer. It had been a month to the day since the video for "Gangnam Style," the first single off his sixth album, PSY 6 (Six Rules), Part 1, was uploaded to YouTube. A satirical ode to his Seoul neighborhood, "Gangnam Style" had all the trademarks of a PSY anthem: an aggressive rap with a catchy hook, coupled with a whimsical dance step and a comedic, over-the-top video.
Like much of his previous work, "Gangnam Style" was very much a PSY DIY: He wrote and co-produced the song and also co-directed the video. In Korea, where PSY has topped multiple domestic music charts a half-dozen times during his 12-year career, the record was an instant hit.
