Restraint- I used to perform live visuals with hardware and it was way more fun to go crazy on on all of the knobs sliders switches fx scratching video and getting extreme with live camera video feedback etc,
But the music didn’t always call for that and if you go all out for the full show it just becomes tedious and has no where to go

Don’t give it all away too fast, so you can save some for the big moment

On the lighting equipment restraint came into play because when someone else got on my board they would want to go all madman on the faders and full blast the fog machine too much. No good

Of course I loved they psychedelic bands, hyped up electronisist etc, way more fun, but I also did solo acoustic act or there would be a slow song or parts of songs and I just tried to match the performing musicians for the best audience experience

With making/playing my own music I don’t care as much, go crazy or not, just have all the fun and not feel guilty about it, but for listening enjoyment I think having dynamic contrast plays out well, ie a loud part seems so much louder after a really quiet part etc, I like a good solo maybe it’s the big moment but probably not best to do that for the whole song simplicity and complexity in music are both great and can be complimentary played against each other, or you can go extreme in one direction or the other, it all has its place

Yes kraftwerk was a great live show, but as I said I like visuals, a concert shot be an experience no matter how you get there. I also like a good guitar solo, virtuosic musicianship, ambient music, and stereolab and other people don’t hear my music so grain of salt ymmv etc
