MCs Choiza and Gaeko make up one of the most influential Korean rap duos in the game. They started out in 2004 with an old-school sound built on disco samples and simple rhymes. Over the years, their flow has become more complex and their music has expanded to include genres like dub and electro alongside their go-to retro beats. Whether they're rapping atop an electronic club beat or a funky R&B rhythm, their songs are guaranteed jams.
