Those lucky Kyunghee students! Son Dambi, After School, Lee Hyori AND Rain?! The hot, sexy and the sexier?! I'm green with envy! The lucky students at Kyunghee University last Friday, 22nd May were treated to performances from the four artists, separately - unfortunately. Hyori and Rain performed, both way long overdue for a comeback, their most recent singles; Hyori's "U-Go-Girl" and "Hey Mr. Big"; Rain's "Rainism," a powerful "Love Story" as well as a throwback to "It's Raining"; Son Dambi performed "Saturday Night" as well as "Crazy"; while After School did "Ah" and "Diva". I'm most impressed that Hyori and Rain both performed with full energy and good vocals, considering they've both been away from the music scene for some time now. I guess that's what you call a "real" artist. I'd hate to be the loser who was absent that day... Let this be a lesson to you kids, stay in school! Your favorite artist might just perform at your school suddenly...! :P Rainism, Love Story and It's Raining. Rainism fancam (ideal view) video credit: biblueberry02 Video message. U-Go-Girl.
