The signs are all pointing in that direction, according to Billboard magazine. Currently, country's top-grossing all-time act is George Strait, with concert sales reaching a whopping $267 million.

The numbers are only going to get bigger with this year's tour, as Kenny has added nine large-capacity stadiums to his concert schedule, including NFL stadiums in Boston, Nashville and Detroit. Kenny's concert promoter Louis Messina boils down Kenny's amazing concert success to one simple factor: "He gives the people their money's worth."
