Casey Fitzsimmons has 4 Brothers Osborne concerts.

Years before they climbed the country charts with songs like “Stay a Little Longer” and “Rum,” the Brothers Osborne grew up in Deale, Maryland, a small fishing town on the Atlantic seaboard. It was a cozy place, filled with blue-collar workers who made their living on the water. During the weekends, many of those workers would head over to the Osborne household, where a series of loose, all-night jam sessions filled the Maryland air with the sounds of Bob Seger, Hank Williams, Tom Petty and George Jones.
