f your reason for not wanting tapers at shows is because tapers are "not at the show, really" since they're so "distracted" and "distracting", then why do you allow people to photograph your shows then?
i don't find either kind of documentation particularly distracting
but i think show taping is sort of dumb and show photography is not
the reason is: rock show photography takes a moving thing and freezes it as a still image. in the process of doing this, some aspect of that moving thing is revealed. in a good picture, the photo reveals something about the moving thing that the viewer would otherwise miss. the camera can get closer to the subject than the audience can get, it can throw the subject into high relief, it can capture things that the audience member cannot see.
rock show taping attempts to capture the most important aspect of a rock show: the audio. but the tape cannot be louder or more overwhelming than the show. it will not sound better than the show. the audience member is far more likely to hear things at the show that will not be on the tape than vice versa.
earplugs, well, life's more fun w/o them, until you come home from a three-week tour and find your ears ring constantly for two months. then you'll want to get fitted for some decent plugs.
