IU is one of the most-wanted guests for year-end concerts this year, but many are starting to wonder why this highly-successful artist isn't holding a concert of her own. IU has never hosted a solo concert, even though it's been three years since her debut. Her achievements and large fanbase could easily allow her to organize one, but IU has decided to take it slow. A related representative informed OSEN on December 27th that�"IU thinks it's not time yet. She would like to show a concert more complete than the one she would show now. Her schedule is packed with album promotions for 'Last Fantasy' as well as preparations�for next year's Japanese debut. If she were to have a solo concert, it would be sometime next year." One thing's for sure -- when IU does decide to announce a solo concert, tickets will sell out like hotcakes. Source: OSEN
