More Visual Music Madness

It may go back to my college days when the engineers at the radio station hooked some black box device to the Christmas tree in the studio. They took the station's audio, ran it through the box and it made different colors light up on the tree. (We tried to make more bass lights turn on. That was the sign of a wonder DJ.)

Neat- and cool, man. (This WAS the 60s.)

Being a visual as well as a musical person, then, these modern day computer-generated things continue to intrigue me. Here's Bach's Sonata in C Major for a solo instrument. It is entrancing to watch the music move as well as hear it.
