You know about the leprechauns and the Irish and the pot of gold, but did you know that St. Patrick's Day has another historical significance in America?

Almost 300 years after the Revolutionary War, the Commonwealth is still Boston strong. While your friends and family may be gearing up for Saint Patrick's Day, there's another holiday that happens to coincide with the iconic Irish holiday.

Whether you've got tickets to the Dropkick Murphys or not, there's plenty of Celtic music to see this weekend.
