This is pretty crazy. But it's a very old video, and I know who took it. It was actually done something like ten years ago on one of those door locks, that you can call each apartment through. It's in my neighborhood, in Vilnius, Lithuania. The guy playing is a friend of mine from back in high school.

I mean it could be a different video with the same kind of door lock, it was Lithuanian for sure because the writing on the door is Lithuanian. Also at one point a lot of people knew how to play that song on those locks. Having a phone with camera was the problem.
