I have seen a couple of tesla HV setups in action and many that are on the net, none of these has had any sort of faraday cage except maybe around someone who was part of the show. The musical setups must be very rich in IMPs.
I have made a test coil and once I power it up I will check out what it is radiating unloaded and loaded etc.
I wandered out in the street yesterday with my Sony 7600, the level of noise on LW and the low end of the MW was quite surprising. On SW the situation was somewhat better but there were still a lot of noises which I assume come from comms/PC equipment in the region below 5MHz.
I attach a pic of the coil, the centre section will be screened as this passes under the AF amp, the fact that the wires are all together in this area should also reduce radiation.
The underside of the coils can be magnetically screened and the battery cases also will act as a screen on the top side. I'm a bit worried about the effect of the shorted turn caused by the casing of the battery.
