The act of Wild-Up is surprise-visiting a location with a classical orchestra. Using perfect coordination to allow for quick set-up of the orchestra, there is not much time needed to play a few tunes. The Wild-op was invented by the Ricciotti Ensemble and is still used to this day.

A wind-up, but way more fun.
I was in the middle of what I assumed would be a regular wind up, when things started getting crazy. It ended as a wild up!
