The third annual Faster Horses Festival in Brooklyn, Michigan, boasts a who’s-who list of country stars. Florida Georgia Line, Brad Paisley and Carrie Underwood will headline the three-day event, set for July 17th — 19th on the grounds of the Michigan International Speedway. This is the fifth festival booking this summer for mom-to-be Underwood, including the inaugural Big Barrel Country Festival in Dover, Delaware.
