The excitement is building leading up to Firefly 2015. Following last month's lineup announcement, organizers have released a day-by-day outlook for the festival, running Thursday, June 18 through Sunday, June 21 in Dover, Del.

Better get your passes quickly, too. In an email, organizers stated "Based on current weekend pass sales, Firefly will sell out at 90,000 attendees this year."

What's more is no single day general admission passes will be offered either. It's all or nothing now, people. Get them before they sell out.
