Earlier this year, Coachella uploaded tons of clips from artist's shows of this year's Coachella to their YouTube channel. One of the clips was Underworld's performing Two Months Off and Dark Train. As a Underworld fan, I loved it!
Sadly, the original video is now private. Why did they do this? I don't know, you also can't reupload the video to YouTube because it gets automatically blocked worldwide by Coachella.
Thankfully, Wayback Machine came in clutch! They have archived the video, so the video hasn't been lost forever to time, yay!
Wayback Machine's servers are a bit slow, so the video may take a while to load. Thanks to this thread for explaining how to access archived YouTube videos via the Wayback Machine!
