On April 17, 2015, KCON said the California convention would expand to a three-day event, and would move from the Los Angeles Memorial Sports Arena to L.A. Live and the Staples Center in Downtown Los Angeles. The convention was preceded with U.S. news reports about the drama and film stars to attend. "People "interviewed "Korean heartthrob" Kim Soo-hyun, Korean American Ki Hong Lee (The Maze Runner, one of People’s "Sexiest Men Alive"), Daniel Henney (Criminal Minds) and Son Ho-jun. Pess called the musical line-up "some of the hottest K-pop artists."It included AOA, Block B, Crush, Got7, Monsta X, Red Velvet, Roy Kim, Shinhwa, Sistar, Super Junior and Zion.T. Billboard noted new group Monsta X after their performance, as a "hot item on the KCON lineup" a group that continued to do a sold-out tour in the U.S. a year later. Billboard gave detailed positive reviews for both night's concerts, and interviewed artists. The Los Angeles Times wrote "the year's most significant concert for one of the world's most fascinating music and cultural scene". "Mega-group" Super Junior's fan base, the "ELFs", were noticed by US media, wearing their blue devil horns. As in previous years, the convention attempted to satisfy attendees, with one South Korea language based institute helping fans write messages of love and support to their favorite stars in Korean.
KCON '15 made plans to expand to New York City for the first time, with an April 24 announcement they would become bi-coastal with date a week apart from the LA convention. A day before opening, Vogue discussed fashion with AOA and VIXX who were busy with a first time "showcase" in Orlando, Florida. Vogue told East Coast K-pop fans to "rejoice...Keep your eyes and ears out for snappy songs and slick dance moves, but above all, for the fashion trends." Organisators said that fans are eager to learn as much as possible about their idols, so the convention tries to provide this, through Q&A sessions with artists by MCs, and "hi-touches" or high fives between fans and band members. Teen Top's appearance made them the first band to perform for three consecutive years;along with Girls' Generation, AOA and VIXX. The New York Times said, "The tears began as soon as Teen Top waved hello," and interviewed passionate fans, some who lined up for the concert at 2:00 a.m.,and attended both the West and East Coast shows. And according to DramaFever, fans watch over 53.9 hours per month streaming videos, compared with about 10.7 hours for Netflix users, are 85 percent non-Asian, and mostly women ages 18 to 24. Fuse TV said the convention attendees were represented by all racial demographics, "women didn't outnumber men the way you'd normally see at a pop music convention", and "teens were out in full force, but not the majority."
