Composed of 1,095 still frames processed through Instagram, this is the first music video, The Plastics Revolution claim, "done entirely on Instagram without any third party alterations." That may well be true for a video professionally produced and shot by a band itself, but there are certainly music videos made entirely or mostly with images sourced from Instagram — Ellie Goulding's video, for instance. And this The Vaccines video for "Wetsuit" relies heavily on fan-shot Instagram snaps.
I wouldn't deny that what The Plastics Revolution and filmmaker Art Perez have done is hard though — much harder than sourcing a bunch of Instagram photos from fans. I set up an Instagram photo booth for a friend's engagement party, and trying to take lots of pictures in a row using Instagram was an unparalleled exercise in technological misery. (Seriously, try it.) So why do it? Because they could, of course. Which is exactly why so many people do so many things with technology. And it looks neat. Does any other reason really matter?
