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.
If you mean taking a quick snooze after fighting traffic in a mad rush to get back home on both the PA and NJ Turnpike, after a shitty 2+ hour commute and scrambling to get parking, in the venue before tunes start, and set up in time then yeah, I relate.
Fortunately, I've learned to deploy both my 2 channel
rig and my open rig in reserved seating shows in about a minute. But the taper anxiety is still real when trying to to juggle work/play schedules for shows during the work week, especially when non-tapers want to try to ride along with me.
I can usually get my 4 chan. rig hooked up in to SBD (plus my Henry PatchBox for other tapers that just want the SBD) and AUD mics in about 5 minutes or less @ venues where I know the FOH/promoters etc. Most gigs I do anymore the FOH already has XLR tails ready for me. 20+ years of taping and building relationships w/ venues pays off...
