Thousands of K-pop fans from around the country amassed in Southern California over the weekend, for the second annual KCON, a festival celebrating Korean food, pop culture and, of course, music, held at the Los Angeles Memorial Sports Arena on Saturday and Sunday.

Last years KCON, which drew roughly 10,000 people, was so successful that event organizers, the cable channel K-pop MNet America, decided to lengthen it to two days.

Attending fans shelling out between $60 and $300 got the chance to attend seminars like "The Arts of Remixing & Sampling K-Pop," "Developing K-Pop Songwriting Skills" and "Get it Beauty: The K-Pop Face."

But for most K-poppers in attendance, it was all about a chance to see their favorite artists like G-Dragon, EXO or Crayon Pop do what they do best.

"Fans see something very positive, whether it's the music, the fashion or the dancing," president and CEO of Mnet America Ted Kim told the Los Angeles Times. "

"This is a really smart audience and they know what's being manufactured and force fed."

KCON 2013 also featured a taping of M! Countdown and an even more extensive list of top notch acts than last year.

But the highlight of the two-day festival was saved for the end, as Big Bang rapper G-Dragon took the stage with American hip-hop superstar Missy Elliott.

"Elliot hit the stage without fanfare for a quick medley of hits like 'Get Ur Freak On' before exiting to admit G-Dragon and generally allow the crowd to lose any shit it still had left after eight acts," Kelsey Whipple wrote Monday on the LA Weekly music blog West Coast Sound.

"The new collaboration between the K-pop heartthrob and the established American hip-hop star is catchy, busy and rife with both posturing and potential."

Other artists on the KCON 2013 bill included 2AM, Super Junior-M's Henry, Dynamic Duo and f(x).

And you can bet that were plenty of fans and stars sharing the "high touch" K-pop's softer version of the high five.  

KCON attendee Christina Tran of Orange County explained the significance of the gesture to Los Angeles Times reporter Ryan Faughnder.

"If [the massive crowds of fans all] could hug them, they would get crushed," the 19-year-old fan said about K-pop stars during 2AM's set.

Tran described the act of sharing a high touch with artists as having an intimate quality.

"You're breathing the same air as them," she said. "It's definitely a fan thing. You can't do that with Chris Brown."
