Not Tesla coils but...
I saw a high-voltage power supply at a laser trade show a few years
ago that was modulated at AF while drawing an arc. It gave a very good
rendition of the "1812 Overture" and was quite impressive. Along the
same lines but many years ago, I read about some audiophile
speakers that used a modulated plasma to produce the sound.
