Since I don't get out too much myself, no. My sister has been to some concerts and stuff, though, like One OK Rock (A kpop group she went to see playing.) and Demi Lovato, although hasn't really met them I think. Joywave, too. She told me she was sitting next to one of the guys, in fact, but didn't know until later. XD Joywave and One OK Rock aren't the most popular, but that doesn't really matter.
Not sure about any of my other family members.
And Sura, you lucky duck. |D (Intentional duck is intentional.)
