These guys built a set of Tesla coils that actually are tuned to be used for musical performance.

The imperial death march, a test of a Faraday suit for a M.C. who performs with the 6 person group.

This video has some good shots of the programmed analog drum set.

From the site:
“Creators of the original Singing Tesla Coils, the crew of ArcAttack uses their high tech wizardry to generate a truly ‘electrifying’ performance. Two custom engineered hand built Tesla Coils throw out electrical arcs up to twelve feet long, each one acting as an instrument with a sound reminiscent of the early days of the synthesizer. A robotic drum set accompanies the spectacle, it’s high power LED’s flashing bright colors with the stroke of each mechanically actuated stick, while ArcAttack’s six members churn out rhythmic instrumental melodies. Live instruments meet drum loops and samples to produce rock, electronica and indie with a splash of punk and a dash of metal served with a side of pop. During the show, the MC engages both the crowd and the Tesla Coils by walking through ½ Million Volt sparks wearing the relatively thin layer of his chain mail Faraday suit. This high power performance is unique in it’s elements and energy, being at the same time mesmerizing and energetically thrilling. “
