DOVER, Del. (AP) – Music fans are descending on Dover for the fifth edition of the Firefly Music Festival.

Campers begin arriving Wednesday at the Woodlands festival site near Dover International Speedway, where 90,000 fans gathered last year for the four-day festival.

This year’s headliners include Two Door Cinema Club on Thursday, Kings of Leon on Friday, Florence + The Machine and Deadmau5 on Saturday and Mumford and Sons on Sunday.

The lineup also includes Ellie Goulding, Disclosure, Blink-182, Death Cab for Cutie, M83, Tame Impala, The 1975, A$AP Rocky, Of Monsters and Men, Major Lazer, Chvrches and more than 100 more acts.

“We wanted the 2016 lineup to reach a wide audience while resonating with our core Firefly community,” said Christiane Pheil, talent and experience director at Firefly, last November when the lineup was announced. “We’re confident this lineup does just that, and we look forward to celebrating our fifth year with music fans from around the world.”

Single day passes to the festival are still available.

If you are going, the Delaware Department of Transportation is offering advice on traffic.
