Millions are put into music videos every year, but decades after MTV first aired, the moneyed gloss can mask a format that is sometimes formulaic and predictable.
But with the emergence of online culture there are new paths open for innovation, and now one French electronic group, Isaac Delusion, has unveiled a unique take on the format.

On behalf of the artists, Studio Clée took archive footage from the Prelinger Archives, which has a collection from over 60,000 amateur, industrial, educational and advertising films. Each iteration of the video is synchronised to the music, but exactly what order it'll play in is down to chance. The catch is, after watching, if the video is not shared that particular combination of footage will be lost forever - ultimately leaving its fate in the hands of the viewer.
A similarly endangered musical project is the Smithsonian and Portugal. The Man's collaboration on "The Endangered Song" - a limited run of vinyl that must be digitised to preserve the music as the records themselves deteriorate over time.

FaltyDL, meanwhile, invited audience participation in a different way by encouraging fans to re-film the music video for "In The Wild" and re-upload it online, changing its form each time.
