Continuing its piecemeal approach to leaking details about its 2014 lineup, Riverfest has today added Chicago, Three Days Grace and Lee Brice to this year’s schedule. They’ll join Hank Williams, Jr., Salt-N-Pepa and Buckcherry, making for one of the strangest festival green rooms imaginable. This year’s festival will be held May 23-25, and three-day passes will be onsale at half-price ($20) starting April 1.
