I saw DMB last night at John Paul Jones Arena ( ) in VA; it was a pre-tour concert in their hometown where it all began with all proceeds going to their charitable foundation. There was no opening act; they played for 2+ solid hours; took a 5 min break and came back and played 3 encores. It was amazing. Not an empty seat; everyone on their feet and dancing/singing along the whole time. Not to mention everyone was friendly and polite and having a great time.
