Florida Georgia Line will be holding their first-ever FGL Fest music festival September 7th at the Indianapolis Motor Speedway. The duo had to wait a year, since the inaugral date was cancelled last year because of bad weather. Joining FGL this year is Dan + Shay, Nelly, Mitchell Tenpenny, Canaan Smith and more. The event takes place the night before the Big Machine Vodka 400 at The Brickyard.
