Kim Hyun Joong's camp told OSEN on December 6, "Due to his drama and fixed schedule, [Kim Hyun Joong] will not be able to participate in the concert. Although it's regretful, it would be difficult to perform due to the scheduling conflict with his filming for 'Generation of Youth'."

DSP Media will hold their first family concert in 22 years, 'DSP Festival', at Seoul Jamsil Indoor Gymnasium on the 14th with its former and current artists, including Sechskies, Click B, Park Jung Min, KARA, and Rainbow.
