If you need to stage a reveal or curtain drop while being absolutely certain that your effect will work perfectly first time every time, you really have no choice about the mechanics: it must be Electro Kabuki.
if you don’t already own EK, you have a choice. Do you hire or should you purchase?
There are arguments in favour of each. It comes down to the scale of your kabuki drop rig or how often you’ll be rigging these types of theatrical reveals.
