I've made plenty of recordings myself where a biathlon-like skill of hustling in, getting situated and rolling, then quickly switching to fully quieting oneself (rapidly slowing breath and all movement) just as the performance begins becomes an important but little discussed stealth taper skill.
Depending on the situation, when in, set, and seated early, sometimes I'll go into semi-obvious-meditation mode, which besides being a good centering quiet-prep and an interesting performance hall listening experience in itself, serves to keep folks who stroll in late and sit adjacent from striking up a conversation that inevitably rolls over the starting announcements and musician tuning, and also seems to encourage a more serious listening mindset in them much of the time.
"Hmmm this guy sitting next to me seems to be rather seriously preparing to listen to this program". Yet another Jedi-stealth influence angle.
