For more musical Tesla coils, check out Arc Attack. These guys are Texans, and have been doing this at Makers' Fairs and Burning Man events for a number of years now. They also got onto "America's Got Talent" last year, where they did "Iron Man" on Tesla coils for Sharon Osbourne (her response: "If you ever cut an album for this, I think I know a singer....").
