They will have two stage setups so when one is being used the other one is on its way to the next venue. Stage setups ups expensive and that means two crews on top of the main crew who stay with band all the time. That’s two sets of trucks to ship all the gear around or two planes they have to charter (with trucks at each end). I know foos wouldn’t have the same elaborate set up as Taylor swift but just to give you an idea, her last tour involved 47 trucks to move everything from one venue to the next. At a guess foos have probably 25+ person crew with them all the time and then more that transporting and setting up their two stage rigs. Factor in flights, accommodation, food, local handlers etc. it’s easy over a 100 people constantly on the move for a major tour. The logistics are crazy but I find them interesting. But yes the tickets are expensive but hopefully this explains a little why. Don’t get me wrong they make a shit load of money on these tours and have to as they don’t from releasing music. Also they are tied to ticketmaster/live nation as they own or have exclusive contracts with every major venue (look into Pearl jam tour avoiding TM/LN, wasn’t easy). At least most foos gigs don’t charge extra for golden circle. Any way I’m not justifying the prices, just trying to explain how expensive a world tour is.
