Firefly Music Festival started rocking today in the woods of Dover, Delaware. The lineup this year is one for the books and everyone better be prepared for some rainy weather to hit the festival over the weekend.

The four-day music festival started off Thursday with some great acts on four different stages. The Kooks, X Ambassadors and Young Rising Sons all opened up the festival this year. I missed today’s acts, but I will be there tomorrow for what I am betting will be some of the best performances of the year.

On Friday, the festival grows to seven stages. Morrissey, Manchester Orchestra and the great Sir Paul McCartney will all perform on the main stage. Manchester Orchestra will also do another show later in the night at the Coffee House stage. Awol Nation and my favorite, Modest Mouse will also be performing on Friday night. Zedd will be playing the late night electronic dance music shift. Be sure to catch different EDM acts every late night.

All seven stages will be in full swing on Saturday with Matt & Kim and Kings of Leon rocking out on the main stage. You can also catch Dirty Heads and Spoon on the other stages. The last day of the festival will host Bastille and the Cold War Kids on the main stage. Snoop Dogg will be performing that night as well on one of the other stages.

Firefly is expected to host around 90,000 concertgoers. Not only do big names make up the line-up, this is a great festival to catch some emerging artists. The highs are supposed to be in the low 80s and thunderstorms are expected to roll in over the weekend. But rain or shine, the show will go on.
