The music video has been around for decades. Thousands of bands have produced millions of music videos, so by now just about every new idea has been done before. But I don't think anyone has ever made a music video... IN SPACE!!!
(despite this logo, MTV never actually visited the moon)
Commander Chris Hadfield, an astronaut aboard the International Space Station, has taken advantage of the fact that he's IN SPACE!!! to do just that. Check out his cover of David Bowie's "Space Oddity", shot, again, ACTUALLY IN ACTUAL SPACE with floating around and everything. Pretty awesome!
In fact, Commander Hatfield's youtube channel is pretty cool, with lots of videos on life IN SPACE!!! as well as other music.
