I’m quite hard to please when it comes to exact synchrony between music and images. I’m sure the abstract animations of Oskar Fischinger were revolutionary at the time, but really have little to do with their soundtracks. Even in modern music videos, sections of close synchrony seldom manage to maintain a coherent relationship between image and music. This seems to only achieve two things: 1) it actually gives greater emphasise the asynchronous elements, and 2) it annoys me.
This video I stumbled across the other day, however, is practically perfect.
