Concerts start too late and end too late at night

I understand that most big concerts are at night, because people are at work during the day and that some concerts are intended to be shown at night because of lights/pryo used during the show. At the same time, if a big show’s headliners starts at 9PM, then by time it ends, you could end up getting back to your house/hotel way past midnight. I think weekend matinee concerts for big shows would be a great idea. Start the headliners act at 3:30 and end at 5:30, perfect to have a dinner after the show.
