Its line-up may not the best in town, but this music festival is perfect for summer—you wouldn't want to splash around in a pool, watch intense water performances while listening to great music in February. Plus, a battalion of food trucks from across the country will accompany the aquatic mirth to provide the sustenance necessitated by unbridled beer consumption. The artists that definitely stand out in the line-up are R3hab, Fedde Le Grand, Bro Safari and Armanni Reign. The rest of the line-up is largely comprised of Korean hip-hop musicians including Jay Park, Loco and Gray. And the best thing? You can enjoy this towering stack of fun for just 30,000 won! So don't hang around—buy a ticket now and think about it later.
