How do you move a large symphony orchestra around Europe? It’s a ballet of trunks and containers. “The payload has its own itinerary, flying from Toronto to Rome to Athens to begin the tour, while the musicians flew through Frankfurt.

It also has its own strict program — an important customs document called the carnet that is as strictly adhered to as any concert personnel chart.”
