Anime and electronic music overlapped quite often in the early years of the musical movement, so even though Porter Robinson and Madeon are among its younger constituents their new music video fits well within the bigger picture. The two producers had already made their eccentricities known during their Triple J interview on the creative process which yielded "Shelter," though, so the fact that they hired an actual Japanese animation studio to create its visual accompaniment comes as no surprise.
The animation was conceptualized and carried out by A-1 pictures in conjunction with Crunchyroll. The former production studio was founded by Mikihiro Iwata, who was the producer of Bandai subsidiary Sunrise, and the latter is a website and online community geared towards East Asian media.
The YouTube video description reads:
Shelter tells the story of Rin, a 17-year-old girl who lives her life inside of a futuristic simulation completely by herself in infinite, beautiful loneliness. Each day, Rin awakens in virtual reality and uses a tablet which controls the simulation to create a new, different, beautiful world for herself. Until one day, everything changes, and Rin comes to learn the true origins behind her life inside a simulation.
With how much Porter Robinson and Madeon seem to have in common, it's safe to expect that "Shelter" will be but the first of many collaborations between the two. While they have yet to announce any upcoming audiovisual spectacles, their fans ought to look out for more in the months to follow.
