"What's your bias?"It's a question only Kpop fans will understand, code words for sussing out if someone else is really a part of the culture. They're referring to their favorite Korean pop bands and/or singers, the same who explode onstage with slick dance moves, addictive beats and colorful outfits.This past Saturday, 17,000 fans came to New Jersey from across the country to celebrate Korean pop music and hallyu (that is, the Korean cultural wave) at KCON's first east coast presence. Held in Newark, the event had food stands, meet and greets, talent shows, panels about the culture and obviously a concert. Fans had a chance to watch their favorite bands, like AOA, Teen Top, VIXX and the mega group Girls' Generation.There was also dancing. Lots of dancing.
