In the Hall of the Mountain King played on Tesla coils

I hate to set up back to back music posts, but this is just too good to pass up. Steve Ward, Jeff Larson and Terry Blake, who bill themselves as the Masters of Lightning, perform songs with solid state musical Tesla coils. They use 25Kw and a MIDI to modulate the break rate (the rate and duration of the high power RF bursts) of the coils to make the music.

Above is their version of In the Hall of the Mountain King. If you go to YouTube they have  other samples such as House of the Rising Sun, Sweet Home Alabama and Dueling Banjos. I wonder what their neighbors think of their concerts?
