Imagine this. It's 1993. 3d computer images are extremely expensive to make and rare, and 3d animations are so time consuming that even the biggest budget movies only use tiny amounts of it. Even 2D computer generated stuff is rare.

The music videos are all just people with greenscreens set against backgrounds of hand-cut film with hand-drawn effects and special lighting and physical effects like smoke-machines. Songs are played with physical instruments, with maybe some electrical processing. And they're about love and tell stories, or they focus on the melodies and combinations of instruments.

And then one day you see this, without warning on saturday morning TV, in between those other music videos:

Hocus Pocus - Here's Johnny (1993)

It was a total mindfuck at the time. Now it's just an adorably quaint and slow-paced historical example of a music video.
