Twenty One Pilots' livestreamed music video set a Guinness World Record

The 'Level of Concern' project ran for almost 178 days.

Twenty One Pilots' supposedly never-ending music video wrapped up last week and it set a Guinness World Record in the process. The band livestreamed a video for "Level of Concern," which pulled in fan-created content from more than 162,000 submissions.

Imposium, which worked on the project with Twenty One Pilots, created a new music video every three minutes and 40 seconds from fan footage and stitched it to the previous one. A moderation team reviewed footage before it was added to the stream.

The project was live for for 4,264 hours, 16 hours, 10 minutes and 25 seconds (almost 178 days) until drummer Josh Dun "accidentally" pulled the plug. That officially makes it the longest music video of all time, beating the previous record holder, a 24-hour-long video for Pharrell's "Happy."
