With ticketing announcements for the 2013 music festival season in full swing, many music fans have been anxiously awaiting news about their favorite music festivals. Fortunately for fans, this week marked the reveal of the 2013 Firefly Festival concert lineup. This is the second annual Firefly Festival and the show hopes to follow in the footsteps of its wildly successful first year. The festival, which takes place at the Woodlands of the Dover International Speedway is scheduled to take place from June 21-23rd. The festival is slated to have acts such as the Red Hot Chili Peppers, Tom Petty and the Heartbreakers, Foster the People and More. Tickets and all day passes for the event will go on sale this month, but those who want to attend the festival live will want to act fast as it is expected to sell out.
