He also put together "The Great Seotaiji Symphony" with Tolga Kashif and the Royal Philharmonic Orchestra to perform his old hits and new songs presented in an entirely new form, combining rock and classical music. The main concert was held at the Seoul Worldcup Stadium. After the main concert, there were complaints about the sound quality not being delivered to the second and third floors at the further ends of the stadium and to make up for this mistake, another encore performance (same setlist) was held in December at a closed/indoor venue, Jamsil Gymnasium upgraded with better sound systems.
