The return of the Carb Night Burger Bash is set for May 26 at Pan Am Plaza. Trent Harmon, who won the final season of “American Idol” last year, is set to perform in what will be his first appearance in Indianapolis. The festival was created in 2008 with the hopes of bringing the drivers of Indycar closer to the fans during race weekend. Most of the 33 Indy 500 drivers will appear this year.
