A sold out crowd of 90,000 spent a sunny, steamy Friday avoiding the mud and enjoying the music at Dover's Woodlands.
Take a look back at some of the highlights of Firefly's first full day of music, capped off by a two and a half hour set from Paul McCartney. While the dust that plagued last year's festival was traded for large sections of mud thanks to recent rains, the weather held off on Friday.
Firefly runs through Sunday night with a performances by Snoop Dogg, Kings of Leon, Foster the People and many, many others. The Killers will close this year's festival on Sunday night.
Next weekend, country music fans will descend on Dover for the first Big Barrel country music festival, featuring headline acts like Miranda Lambert, Blake Shelton, and Carrie Underwood.
