Bjork, "Bachelorette" - This is what hooked me on Gondry. The vivid depiction of a mediated life whose only content is the mediation. Told in ~five-and-a-half minutes.
Cibo Matto, "Sugar Water" - "Bachelorette" was dazzling in its structural recursion and slight social commentary. "Sugar Water" presents a similar structural coup in a split-screen crab canon. Instead of looking forced or overly technical, it is thoroughly enjoyable. Like one of the YouTube commenters, I have to admit that I don't fully understand how Gondry pulled it off. Stunning.
