As most of you know, Chester, from linkin park, committed suicide in the summer of 2017. If you look at some old tweets from Chester, you can see that he was a fan of Twenty One Pilots. I, and many other people on the internet, thought it would be cool to pay tribute to Chester, and Linkin Park, by Twenty One Pilots doing a cover of one of there songs, either in the album, on tour or as an official song like they did with Cancer.
