Dumb question is it also creating the piano like sound in that video with the electricity? Very cool to watch.

  Yes! That's all done with the plasma channel expanding and (therefore) contracting at audible frequencies. (edit: I'm way wrong on the piano. arjie's correct about the backing track)

  There's a backing track.
