"Music videos are the closest thing to manual labor musicians have to do," Twenty One Pilots frontman Tyler Joseph kicks off the above video. "And for me, it just takes it out of me."

It's a somber start to a somber clip: the duo, Joseph and drummer Josh Dun, are preparing to film the official music video for "Heathens," their Suicide Squad single. "I couldn't really sleep a lot last night because I'm really kind of anxious," Joseph continues, "but I'm excited."

We'd say it gets better from there, but if you've seen the "Heathens" video, you know it deals with some heavy stuff. The guys give us a peek into the filming process, the grim and the great.
