Plasma Phonic is our “rock band” of musical Tesla coils and robotic instruments. After polishing our techno-entertainment chops, we rose out of the Sonoran desert and burst onto the live performance scene with our 2013 debut at the Playboy Mansion Halloween Party. We mix a unique blend of cover music ranging from retro to contemporary.
