SexyBack vs. Legend of Zelda Theme on Two Tesla Coils from Trammell on Vimeo.
At SXSW this year, ArcAttack set up Tesla Coils to act as synchronized instruments in a massive custom DJ setup. According to ArcAttack, these Tesla Coils produce an electrical arc with a distorted square wave sound that mimics early synthesizers. They then manipulated the wave in such a way to play back the theme to The Legend of Zelda.
