If the world were a just place, Brandy Clark would have played one of the festival's headlining slots at the stadium, buoyed by a huge radio hit. Nevertheless, it was a welcome sight to see throngs of people heading over to the Chevrolet Riverfront Stage to catch her outstanding daylight set. To match the lively outdoor atmosphere, Clark and band primarily stuck to her rowdier numbers, like Big Day in a Small Town cuts "Love Can Go to Hell" and "Girl Next Door," closing with an especially twangy take on "Broke." She may not have that coveted radio play just yet, but perhaps Clark doesn't need it: she's a star on any size stage. B.M.
