First Elvis, then Tupac, and now Girls' Generation? SNSD held a special surprise concert over the weekend at Gangnam Station in Seoul. Special, in that the ladies themselves weren't actually there—they appeared as holograms! The "V Concert" was to help kick-off their fourth studio album, I Got A Boy. Virtual avatars of the ladies were present for fans while the ladies themselves live-streamed a chat from a nearby recording studio. See video of the incredible performance here: Amazing, right?
