Singing-Music playing Tesla Coil - What is their future?

I have heard about Tesla coils used for music creation/reproduction. I haven’t seen any discussion on this forum. Does anyone have further information concerning the future use of Tesla coils in music production and reproduction?

I have found that Tesla Coils can and this on 5 songs and even better music
Ted Denney has been using a monster Tesla coil to condition a lot of his components for years now. Speaker cables, interconnects, power cords, outlets. 
I have blue fuses, blue outlets and 32 HFTs of which the outlets use the coil.  Great tweaks.  However, does anyone see a future for powering/connection of equipment or as a musical instrument for serious composition?
