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, bungee bounce and water limbo 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. One artist that definitely does stand out in the lineup is Tinashe, one of Billboard's top R&B artists of the year. The rest of the line-up is largely comprised of hip-hop musicians like Korean rappers Dynamic Duo and talented producer Primary. And the best thing? You can enjoy this towering stack of fun for just 10,000 won! So don't hang around—buy a ticket now and think about it later.
