Kenny Chesney has sold out his July 14 concert at Madison Square Garden, becoming only the second country artist to do so. (The Dixie Chicks were the first in 2003.) Tickets were gone in an hour. As previously reported, Chesney also sold out his July 16 show at the New England Patriots' Gillette Stadium. He's currently on The Road and the Radio tour with opening acts Dierks Bentley and Sugarland.
