Riverfest has announced its first three 2014 headliners, and it’s a diverse bunch: Hank Williams, Jr., Salt-N-Pepa and Buckcherry, three acts with impressively non-overlapping fanbases. This year’s festival will be held May 23-25, and three-day passes will be onsale at half-price ($20) starting April 1. Check back next Tuesday for the next three headliners.
