This guy found yet another weird way to cover Toto's"Africa". He programmed Tesla coils to play the song . . . and the most interesting part is there are NO speakers or special effects involved.
According to the post, the coils are playing the music "due to the programmed phase, pulse width, and firing frequency." Whatever. It sounds and looks cool.
(Search the Franzoli Electronics on YouTube for "'Africa' By Toto On Musical Tesla Coils." He's got several other songs on there as well.)
