Yes there is a shuttle. You can use it at any reason to get to that area. It goes on the hour and you must call by 10:30pm for the last shuttle
They do have a shuttle that goes to Heinz field for games so I'm sure a concert wouldn't be an issue. But they stop running after a certain point so you may not have shuttle back...
They have a shuttle that goes into town. Not sure if they do specific events
