Twenty One Pilots have performed in Korea a few times over the years and have spoken about their love for the Korean language and culture, even including some Korean in the intro to their song Tear in my Heart. I have also used snippets from a demo called 'Korea' that was used in a Korean tour doc (   • twenty one pilots - Korea (demo)  ).
