What does an orchestra strike look like?

Are the pianist and tympanist on mounted drones or like, do the heavies stay in cover while the flautists, tromboners, and violinists charge out on foot to make some noise?

(Look, I know. But I chose to interpret it this way. Because a greedy orchestra owner should start quaking in their monocle whenever they hear Flight of Valkyries while walking around seemingly empty streets at night.)
