I think that the quote was rather about the fact that some industrial projects, no matter how good they sound, look quite boring live, because the viewer doesn't see any action in it, a "show" if you will. Running the phonogram from a laptop, occasionally using a couple of pedals and freezing in a static position on stage - it in my opinion is justified only in Ritual/Ambient genres, where everything should correspond to a leisurely and smooth flow of sound.
If we are talking about Noise/PE, first of all I personally always want the performer to recreate on stage that is express by his sound. There are guys who like to dig through wires on stage and press buttons to the roar and screech of a synthesizer, and it could pass for "knowing how to play an instrument in noise", but in my opinion, it's much more important to be able to perform. You don't have to roll around like Masonna, or broadcast some blatant extreme, but in my opinion the performance should keep the audience engaged.
Sometimes instrumental bands in different genres look weak on stage, even though they play their instruments professionally. What to say about the noise
