If you want to know what heaven sounds like, just cover a Mini Cooper in harmonicas.

These guys were tasked with doing a promotional stunt for Mini Cooper. Apparently leaving the whole “figuring out what to do” thing until the last minute, they settled on a bizarre plan — one that accidentally unlocked the true sound of what’s behind the pearly gates.

After painstakingly applying all of the harmonicas (and making sure that they won’t fall off and shatter someone’s windshield), the team goes for a drive. And, my God, is it beautiful.
